The Magic Mike XXL star turned 40 on Dec. 28, kicking off his late birthday festivities Friday night at the W Hollywood. Along with his wife, Sofia Vergara, the two later took to Instagram to share highlights from Manganiello's rockstar-themed "Joechella" bash.
"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."
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.
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!
