Ashley Tisdale & Patti Murin: Laughing Ladies

Ashley Tisdale gets the giggles after lunching with Patti Murin on Tuesday afternoon (April 17) in Studio City, Calif.

The two actresses are currently working on an untitled comedy from Louis CK/Spike Feresten at CBS.

Ash stars as Petra, a beautiful and sarcastic assistant to a vintage clothing designer struggling to carve out her niche in New York.

“And we are WRAPPED! Again. It was a fun 19 hours in LA :)” Patti tweeted.

FYI: Ashley is wearing Koolaburra‘s “Jessie” boots.
