Beverly Hills 90210 star Jason Priestley's career has eased off in recent times - and so has his grooming regime.

The actor, who played fresh-faced heartthrob Brandon Walsh in the hit show, arrived at Nike's 10k global Human Race in Los Angeles looking decidedly unkempt yesterday.

He kept himself hidden behind a Grizzly Adams style beard which left him almost unrecognisable from his 1990s heyday.

Jason, who starred in the show for nine seasons and remained an executive producer until the end of the original series, didn't seem particularly thrilled about the new incarnation of 90210, which debuted in the US this week.

He said: "Am I looking forward to it? Er, I'm intrigued by it. I think, like, I'm intrigued by it, sure.'

When asked if he'd like to rejoin his former co-stars Shannon Doherty and Jennie Garth on the show, Jason bluntly replied: 'Er, not really no.'

And when a reporter asked if he believed the show should have been brought back, he said simply: 'It's none of my business, really is it?'
