It's official - Sarah Michelle Gellar's hit TV series Buffy The Vampire Slayer is set to end once its current season wraps. After seven years, the massively popular cult series is set to come to an end in May. Gellar concedes, "Buffy, in this incarnation, is over." The series will wrap up with a five-part story, which will include the return of Faith, the bad-girl slayer, and Buffy's first love, Angel. Gellar says, "We're gearing up to tell a fabulous, huge, great arc. It's going to be pretty spectacular." But the show may come back to life in some form - its creator, Joss Whedon, is planning a spin-off that may include some Buffy cast members. Gellar gained fame on the cult hit as Buffy Summers, a perky high school student burdened with the responsibility of killing vampires in the seemingly idyllic town of Sunnydale, California.

Bruce Willis has fought bad guys, saved the world and seen dead people on the big screen but he faced his toughest challenge on TV in America Wednesday night. The movie hunk, who was scheduled to appear on The Late Show to promote his new film Tears Of The Sun, found himself hosting the show when chat show titan David Letterman phoned in sick - with an eye infection. Admitting he was terrified, Willis did a good job of hosting the hour-long late- night show, interviewing news man Dan Rather about his chat with Saddam Hussein and Baywatch babe Carmen Electra, who was brought in at the last minute to help boost the show. The actor also had fun playing harmonica with Letterman's house band, took out his frustrations by smashing up a pile of CDs with a sledgehammer and even dressed up for a skit to promote his new film, in which he pretended to be a number of different people raving about his new war film. But there was no mistaking his nerves at the beginning of the show. He said, "I am not David Letterman, I'm Bruce Willis. Dave is home with a little eye problem and I couldn't be more honored and I couldn't be more scared to death to be here." Never one to miss an opportunity to promote a new project, Willis closed his stint as a late night TV host by saying, "I've just spoken to Dave on the phone and he doesn't want cards or flowers or any of that junk. He just wants you to go and see my new movie Tears Of The Sun on March 7."

Actor Robert Blake is convinced he's set to face the death penalty for killing his wife - even though his murder trial is only a day old. Blake appeared on American TV Wednesday night for a taped interview with broadcaster Barbara Walters, where he confessed he felt that no one in the world thinks he's innocent of Bonny Lee Bakley's death in 2001. Tearful and frustrated, he told Walters, "You couldn't find 12 people at 20,000 feet in Tibet that wouldn't say, 'Is that man still alive? I thought we killed him already. Well, hang him and get it over with.'" And when Walters asked him if he thought people really thought he was guilty, the Baretta star raged, "What do I care? How do you kill a dead man? What are they going to do to me that they haven't done already. They took away my entire past, they took away my future. What's left for them to take? Are they going to take my testicles away and make earrings out of them?" Blake also used the interview, which was filmed last week from the prison where he has been incarcerated for almost a year, to rage at the justice system which has ruined his life and threatened his baby daughter Rosie's future. He fumed, "I'm going to take Rosie in the park and let all them people say, 'There's the murderer. What's he doing with that baby?' I don't think so."

Sexy actress Heather Locklear has finally been snapped up by a TV network - following a break since her hit show Spin City ended last spring. America's NBC has managed to secure the services of the small screen beauty for a new sitcom tentatively titled Once Around The Park, which will see Locklear playing a divorced mother of two children. Most major TV networks in America had been chasing Locklear since her show went off air and she was on the verge of signing up for now-defunct show Hub - but pulled out because she didn't want to relocate to Texas. At one point, her representatives even considered landing a seven-figure talent- holding deal for Locklear, but ultimately decided to hold out for a specific project. The demand for Locklear is hardly surprising: almost every series she's been in - including Dynasty, TJ Hooker and Melrose Place - has been a success, often only after she joined the cast.

Superstar Jennifer Lopez has rubbished reports she and fiance Ben Affleck canceled a planned Valentine's Day wedding. It was suggested the celebrity couple were set to cap off their whirlwind romance by tying the knot in a spectacular ceremony in Puerto Rico on the most romantic day of the year. When the Hollywood wedding of the year didn't take place, it was assumed the couple's relationship was in on the rocks. But J.Lo - who met her hunky husband-to-be last year on the set of Gigli, the first of the pair's two 2003 movie collaborations - insists the rumors were fabricated by American supermarket tabloid Star, before spreading around the world. The actress says, "It was not put off. The whole February 14 story was a made up thing by the tabloid."

The sequel to hit film Bridget Jones's Diary will go ahead with star Renee Zellweger - according to her body double. Despite Zellweger's insistence that she has yet to see a script for The Edge Of Reason, as well as co-star Hugh Grant's prediction that a sequel will never happen, a body double has already been booked for filming. Melinda Whiting, who worked on the massively popular original, confirms that she will work on the new movie - intimating that Zellweger will reprise her role as the luckless British singleton. A source reasons, "Melinda's definitely booked up to feature as Renee's double again and she is certain Renee is due to appear, otherwise why would they want her?"

Hollywood heart-throb Josh Hartnett has added a high level of turbulence to the long-awaited revival of Superman - by turning down the chance to play the superhero. The Black Hawk Down star, 24, was pitched as the ideal contender to take over from Christopher Reeve's portrayal of the Man of Steel, but the actor has decided to opt out of Warner Brothers' offer. Remaining candidates reportedly include Brendan Fraser, Paul Walker and American soap star Matthew Bomer.

Comedian Robin Williams has ridiculed Michael Jackson's claims he was the victim of racism at the hands of record label Sony - because the pop superstar doesn't belong to a race. Jackson made the shocking allegations after his album Invincible filed to rack up the anticipated sales when it was released in late 2001. But the former Mork & Mindy star insists the 44-year-old Bad singer can't be racially-discriminated against, because the now fair-skinned African-American star doesn't belong to any race. She says, "Michael Jackson's standing outside Sony with a sign claiming racism. I said, 'Honey, you gotta pick a race first. All of a sudden you're a black man, then you're Diana Ross, now you're Audrey Hepburn. Then he's got the little beard going on. He's like Lord Of The Rings, the entire cast. Michael's about to jump species."

Justin Timberlake is set to explore his feminine side on American TV - in hit sitcom Will & Grace. TV executives have written the gender-bending script especially for the pop hunk, ex-boyfriend of sexy singer Britney Spears. In the award-winning comedy, the 'N Sync frontman will play a scheming gay gigolo who steals the heart of flamboyant Sean Hayes's character Jack, and swindles him out of money. The 22-year-old singer reportedly plans to donate his $50,000 paycheck from the show to an AIDS organization.

Legendary rockers Simon And Garfunkel could be willing to put a bridge over their troubled waters and team up for a summer 2003 concert in New York's Central Park. The duo reteamed for the first time in 20 years at this year's Grammy Awards but reportedly had a blazing row during their afternoon rehearsals. However, reports suggest that the hitmakers may be prepared to share a stage this summer for the one-off gig. But it is unlikely to lead to a tour. Recent rumors that Paul Simon - who wrote all the duo's hits - isn't prepared to allow Art Garfunkel an equal share of earnings have been scotched and it seems his busy schedule is the real reason there will be no long term collaboration. A source says, "Money has never been an issue. Paul would be willing to give Artie half. The truth is, Paul's simply too busy with his own solo album and doesn't have time to hit the road."
