Joe Jonas celebrated his birthday in style over the weekend, by partying with friends in Sin City.
The Jonas Brothers star turns 22 on Monday, and to mark the occasion, the singer enjoyed a fun-packed day on Saturday in Las Vegas.

Jonas began the celebrations in a VIP area at the Liquid Pool Lounge with a number of close pals, before moving on to the Bellagio Hotel’s Yellowtail Japanese Restaurant & Lounge, where he dined before taking the party on to the Deuce Lounge to play blackjack.

Jonas ended his night by performing at nearby venue Haze, where he was handed a surprise birthday cake, reports

A source tells the website, “Joe was swarmed by nearly 20 female fans dying to get an autograph or photo with (him). After signing a few autographs and meeting with fans, Joe finally made it to Haze Nightclub where he rocked the crowd with a special live set, performing tracks off of his debut solo album FastLife.

“Joe was completely surprised when he was presented with a specialty pre-birthday cake in the shape of a bright-colored keyboard. Partygoers were holding up sparklers and shooting confetti into the air while toasting Joe to another successful year.”
