Simpson also told Extra that she is ready to start getting out and having fun again.
"I just shot a video a few days ago called 'I Belong to Me,'" she said. "It was a very emotional time for me, and I think the people will experience what I've been experiencing for the past year when they watch it."
All the pop starlet would say about her upcoming "Working Girl" remake was that she couldn't wait to do it.
"I'm so excited about it," she said. "People are going to laugh."
