Ashley Tisdale at the premiere of “Phineas and Ferb: Across the Second Dimension"

She’s had a busy summer, and on Wednesday night (August 3) Ashley Tisdale was spotted at the premiere of “Phineas and Ferb: Across the Second Dimension.”

For the film, Ashley teamed up with a host of wonderful talent, including Kevin James, Sigourney Weaver, and Dee Bradley Baker.

“Phineas and Ferb: Across the Second Dimension” is about Perry's worst fear coming true when Phineas and Ferb finds out that he is in fact Secret Agent P, but that soon pales in comparison during a trip to the 2nd dimension where Perry finds out that Dr. Doofenshmirtz is truly evil and successful.
