George Clooney and Steve-O's ex-girlfriend Elisabetta Canalis got on all fours while tanning her slammin' single body in a purple bikini in Cannes on Tuesday.

From the glorious looks of it, she won't be sans boyfriend for much longer.

The mystery is over ... Steve-O and Elisabetta Canalis are DEFINITELY more than friends ... and yesterday they engaged in a little mouth-on-mouth PDA to prove it. 

There was a fierce debate in our newsroom ... some people felt that Elisabetta's decision to date the "Jackass" star is a step down from George Clooney. Others think she's decided status symbols don't bring happiness ... and since she might be happier with Steve-O, it's NOT a step down.

So, we gotta ask ...

Elisabetta Canalis and Steve-O went to a HAIR SALON this weekend ... TOGETHER ... so, it's fair to assume they're totally dating now, right? 

Rumors have been swirling for weeks ... that George Clooney's ex-GF and the "Jackass" star have been getting pretty up close and personal in the past few weeks.

The two hit up Trust Hair Salon in West Hollywood on Saturday ... and as they both got into Steve-O's car ... we asked if they were officially more than friends.

They didn't have to say anything ... it's pretty obvious.

Mehcad Brooks might be the next George Clooney ... maybe ... because the "True Blood" star had a romantic dinner with Clooney's ex Elisabetta Canalis this week ... and TMZ has the video to prove it!

The two dined at STK steakhouse in L.A. -- and after what seems like a date, they BOTH left in Mehcad's SUV.

Before Brooks and Elisabetta drove off together, we asked Mehcad, "How did you guys meet?" He cracked a big, GUILTY smile ... and joked, "We didn't meet ... I have no clue what you're talking about."

So, we gotta ask ...

George Clooney is doing something he almost never does -- commenting about a report on his romantic life ... in particular, one that claims his ex-gf sent him angry text messages about his new gf.

The report in the current issue of US Weekly ... claims Elisabetta Canalis fired off a series of angry texts to George when she found out he was dating Stacy Keibler.

But George tells TMZ, the story "was completely fabricated in order to sell magazines. I never comment on my personal life unless it affects others...and this lie affects others."

George added this challenge to US Weekly, "Since I would be the only actual witness, I ask you to correct your story immediately, but that would assume you cared at all about telling the truth."

George Clooney's on every woman's "list" of guys they'd get a pass to cheat with -- so maybe Elisabetta Canalis was exercising her Clooney clause before returning to her other guy!

George Clooney's ex-girlfriend Elisabetta Canalis looked like she didn't have a care in the world while sunbathing in Italy this weekend.



When you look like Elisabetta it's hard to be too upset about anything.

Before becoming a single, unattached man again, George Clooney  was with his ex-wife Talia Balsam, French actress Celine Beltran, British model Lisa Snowdon, Las Vegas waitress Sarah Larson and, most recently, Italian actress Elisabetta Canalis.


Question is ...

George Clooney only gets down on one knee ... to tie his shoes. Yep, add Elisabetta Canalis to the list of women who've failed to get Cloons to the chapel -- but be sure to soak up the view as she exits.
