"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."
