"When I started the fourth season, I kind of had a talk with the producers," she revealed toE! Online last week. "We didn't know what we were going to do with the characters. After playing someone for four years, it can be a little repetitive. So I was ready for a change."
That change meant it was time for Vanessa to go. "I had so much fun and I made friends I'll have for a lifetime and it was so great to work in the city, but I got the most I could out of Vanessa."
Jessica is open to a possible return next season, but don’t expect her to show up right away. She’s shooting movies in July and August, and likely won’t be available. We won’t hold our breath.
