Couples Therapy actress, Kristin Davis, has been hard at work promoting her film with Vince Vaughn and Jon Favreau. In fact, the stylish star recently popped over to David Letterman‘s talk show for an interview.

However, when the Sex and the City star chatted with MTV News, she was tight-lipped about revealing any plot secrets. Davis responded to pressing questions by saying, “I definitely cannot answer that question based on the three-page legal document that I signed relating to such things.”

However, Davis did oblige with a few tidbits by admitting that while Charlotte would no longer be suffering from the digestive problems that plagued her in the first movie, her marriage to Harry might be facing some troubles. As for the 80s garb, Davis admits that it’s not just a flight of fashionable fancy and that “here’s a good story of why we’re in it.”

She’s such a tease.
