"Thanks to everyone that made it out tonight!" Manganiello captioned a pic of the party invite, modeled after the artwork from the Coachella Valley Music and Arts Festival. "And thank you @djhapa & @steelpantherkicksass for bringing down the house!!! #JOECHELLA 40."
He also showed off his birthday cake -- a bright red, black-and-white striped Van Halen guitar!
An eyewitness tells ET, "[Dennis] Rodman got on stage for a couple of minutes and sang. Fergie danced with Sofia [Vergara] for a while. Joe [Manganiello] got up on stage later in the party and sang." At one point, the guest of honor even sang Backstreet Boys' "I Want It That Way" with Michael Starr from Steel Panther.
And according to Starr, Vergara hopped on the mic, too, belting out some Bon Jovi. "Sofia, you sang Bon Jovi great," he gushed. "Fergie chickened out lol."

Vergara looked stunning all night, sporting a sweetheart jumpsuit and sparkly choker, while her beau wore a Guns N’ Roses T-shirt and distressed jeans.
"Rockstars!!!" she captioned a pic of Starr and singer Fergie in action.
And what would a night out be without snapping pics inside a photo booth?
The eyewitness also observed Manganiello and Vergara share several cute moments throughout the night. "They danced together, kissed and held hands," the eyewitness explained. "It's clear they're in love." Others in attendance included Josh Duhamel, Pee Wee Herman, Jesse Tyler Ferguson and Eric Stonestreet. See more highlights from the bash below!
