Ashley Tisdale keeps it cute in blue and white stripes as she attends her very first panel at the 2011 San Diego Comic-Con on Friday afternoon July 22. The 26-year-old actress joined costars Vincent Martella (Phineas), Olivia Olson (Vanessa), Dee Bradley Baker (Perry) and creators Dan Povenmire and Jeff “Swampy” Marsh at the Phineas & Ferb panel. “Comic con was Awesome! Loved seeing all the passionate fans. Such a great first experience #nolongeracomicconvirgin,” Ashley tweeted afterwards. Ashley also recently spoke to InStyle about BFF Vanessa Hudgens new hair. “I think it looks elegant on her—very cool and pretty. Her hair has been the same way for so long. It’s so great for her to change it up. I think she looks beautiful no matter what,” she shared. Check out the pictures below.
