Ashley Olsen Is Socially Challenged

The super private Ashley Olsen showed up on 'Good Morning America' to promote her and Mary-Kate's new coffee table book Influence.

During the interview Ashley told Diane Sawyer that she's socially challenged and has a hard time with big groups and being in public in general.

She explains: "I'm really not great with crowds or big groups or public speaking. I just get very anxious. It's just something about being in front of that many people. I guess I black out - I never really remember how an interview went."
