AnnaSophia Robb and Austin Butler.What's the toughest part of AnnaSophia Robb's role on the CW series The Carrie Diaries?

Playing Austin Butler's love interest, apparently!

"One of the biggest challenges for us is to be sexy and flirty on camera because we just can't take each other seriously any more...kissing on camera isn't that fun!" she explains in the latest issue of Seventeen. "But he's so cute! He talks about Vanessa [Hudgens] all the time!"

But AnnaSophia says she's not sure she's ready for a relationship as serious as theirs.

"They're crazy in love!" she shares. "I don't think I'm ready to be that in love. They put so much time into their relationship, and I'm too selfish right now."
