Halitosis heartthrob Matt Damon

Matt Damon has bad breath, according to Sarah Silverman.

The American comedienne - who famously created a video entitled 'I'm F***ing Matt Damon' for her TV host boyfriend Jimmy Kimmel in 2008 - joked the actor's breath was not the freshest she'd ever smelt, while honouring him with an award on Saturday night (27.03.10).

Sarah claimed she'd given Matt "his first really big break" in the video, which was aired on US TV before becoming an instant YouTube hit, and added: "The worst thing I could say is, you know, Matt Damon is, like, a perfectionist. And his breath is like, Jesus! And his hair plugs are really obvious. Besides that, there's, like, nothing."

The 39-year-old actor - who was honoured in Beverly Hills with the 24th American Cinematheque Award - was continually ridiculed all night by several of his celebrity friends.

Actress Charlize Theron joked the Hollywood heartthrob was to blame for one of Will Smith's box office flops.

She said: "In 2000, Matt and I starred in 'The Legend of Bagger Vance' along with Will Smith, the only Will Smith movie that didn't make, like, a million dollars. I reunited with Will in 'Hancock', which did great. So I guess it's you, Matt."

Referring to his 1997 Oscar win with Ben Affleck for Best Original Screenplay for 'Good Will Hunting', she added: "That's not the only thing Matt and I have in common. We're both Academy Awards winners. Of course, I won mine in a real category and Matt's was just for typing up Ben Affleck's thoughts."

George Clooney also starred in a strange video shown during the celebrations at the Beverly Hilton Hotel, which featured him making a speech while undergoing a mock proctology exam.

Afterwards, Matt said: "That was particularly enjoyable - and strange!"

The tribute for the star will be shown on US TV network ABC next month.
