Jennifer Lawrence had to undergo about eight hours of makeup application a day to play Mystique, a blue-skinned, shape-shifting mutant, in the new X-Men reboot, 'X-Men: First Class.' She talked about the process Friday on 'Live With Regis and Kelly' (weekdays, syndicated), and also let it slip that she is dating another actor.

Lawrence said she had to either stand or sit on a bicycle seat nude while the blue body make-up dried, something that piqued the interest of Regis Philbin, who is letting his inner creepy old man show through a bit on his run up to retirement. "Just trying to put it all together," he said, furrowing his brow.

Jesse Eisenberg admitted on 'The Tonight Show' (Weeknights, 11:35PM ET on NBC), that he has some quirks that affect his daily life, and that he has even more severe rituals he must perform before coming onto a show like this one.

It sounds like a form of obsessive compulsive disorder (OCD), but at least it's manageable, and it's good that Eisenberg is comfortable enough to talk about. What he probably would have never expected is to find someone who's actually jealous of his quirks.

Jennifer Lawrence was Jay Leno's next guest, and she immediately turned to Eisenberg and said, "By the way, you are the most interesting person."

Apparently while watching him from her dressing room she decided, "I want weird quirks."
