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.
