Linda Perry and Sara Gilbert -- Wedding? More Like a Rock Show with Vows

I went to an 80s rock concert this weekend and a wedding broke out ... is how guests at the nuptials of Linda Perry and Sara Gilbert must have felt ... because the affair was JAM PACKED with rock performances. 

Perry and Gilbert tied the knot in Malibu on Sunday, after announcing their engagement a year ago.

According to our sources, Sharon Osbourne, Julie Chen, Aisha Tyler, Steven Tyler, Juliette Lewis and Tobey Maguire were all in attendance. 

But the stars of the show were the people who took the stage, backed by 80s cover group Flashback Heart Attack:

-- Tobey Maguire's little daughter Ruby sang "Girls Just Wanna Have Fun"
-- Annabella Lwin from Bow Wow Wow sang "I Want Candy"
-- Martha Davis from The Motels sang "Only The Lonely"
-- Missing Persons' Dale Bozzio sang "Destination Unknown" and "Walking in LA"
-- Terri Nunn from Berlin sang "The Metro" and "Take My Breath Away" (!!!)
-- Linda joined Terri on stage to sing "Sex (I'm A…)"  
-- Terri finished with "Highway to Hell" 

Our sources say Linda MC'ed the whole show and the stage was mocked up to look like the classic rock club CBGB.

Way better than dancing the hora.
