According to Star, the Olsens have said NO to a guest appearance on Stamos's new show, Jake In Progress. Apparently they said no because they wanted to concentrate on their studies and other current projects like their new furniture line. Considering the source, there is speculation that there was ever even an invitation to the twins in the first place.
Maybe this is a PR stunt about the PR show that needs higher ratings to secure being picked up for the fall season. Olsenâ€™s or not, the sexy show is fun and has potential celebrity cameos in the future - I think Bob Saget is free.
