Pink made her first public appearance after gall bladder surgery on Wednesday night (13Jun12) when she joined husband Carey Hart at a charity comedy concert in Los Angeles.

The stars were guests of honour at PETA's Stand Up for Animals fundraiser.

Glee actress Jane Lynch and hard-hitting political comic Bill Maher were among the celebrities who hit the stage at the Comedy Store.

Animal-loving comedy fans Olivia Munn, Cloris Leachman, Jorja Fox, SethMacFarlane, Elisabetta Canalis, Emily Osment and Moby joined Pink and Hart in the audience.

Pink had to scrap a performance for U.S. President Barack Obama in Los Angeles last week (ends08Jun12) after falling ill, resulting in having her gall bladder removed in hospital.
