Larson: 'Dating Clooney Was Stressful'

The former cocktail waitress admits she loved dating the former People magazine Sexiest Man Alive, but the romance wasn't always a hoot.

In her first in-depth TV interview about her relationship with the movie hunk, Larson tells U.S. news show Access Hollywood, "It was a little nerve-wracking because everybody loves George, and so, to be in the public eye like that, it was a little bit stressful.

"It's a lot to take in. I think I just went like a deer in the headlights. At times, I (didn't) know what to do."

The pair dated for almost a year and Larson reveals the break up was fast, and she hasn't kept in touch with her famous ex: "I haven't spoken with him in a very long time. (It's) not necessarily that there's hard feelings but we just haven't... When you break-up, it's difficult but you move on."

And she's determined not to become a kiss-and-tell lover: "Out of respect for George, I know how personal he is and so I really do try to avoid as much of that as possible, because I know that he's a very personal guy and I would never wanna do anything to make (him) uncomfortable."
