It�s True! Elisabetta Canalis shared a kiss & grabbing her new beau's backside

She dated Hollywood's most suave star George Clooney, but now Elisabetta Canalis has started a surprise romance with Jackass daredevil Steve-O.

The Italian beauty, 33, confirmed the rumours as she leaned in for a kiss with the goofy TV star after having lunch together in Hollywood yesterday.

A day earlier the two celebrities seemed coy and would not answer questions about their relationship status in a video posted on TMZ.

But they certainly weren't shy about showing their affection yesterday.

The former Dancing with the Stars contestant, who was dressed in a white maxi-dress, sat on her 37-year-old beau's lap and at one point grabbed his backside.

Insiders say Steve-O's sense of humour won her over. 

'Steve makes Elisabetta laugh, and that's her weakness,' a source tells Radar Online.

'That was her favourite thing about George Clooney-he was always cracking her up and playing practical jokes on her.

The source adds: 'Ever since Steve-O got sober, he's very sensitive and introspective, so Elisabetta is getting the best of both worlds.

;They're not serious yet, but they are definitely hanging out, and hooking up. They are trying to stay under the radar, so they mostly hang out at her place and watch movies and order in. But they also hit some low key restaurants around her neighborhood too.'

For nearly two years the Italian TV star was in the enviable position of dating one of Hollywood's most eligible bachelors.

But in June last year Canalis and Clooney, 50, announced they had split. The Oscar-winner is now dating former wrestler Stacey Keibler.

Steve-O - whose real name is Steven Glover - is well-known for being part of the outrageous Jackass cast that made a name for themselves on MTV.

In March 2008, the London-born former stuntman, was placed on 72-hour psychiatric hold after friends worried that he was a danger to himself.

His controversial stunts include lighting his head on fire, swallowing live goldfish and trying to vomit them up alive.

Both Canalis and Steve-O have competed in the US TV series, Dancing With the Stars.
