Happy Birthday Joe Jonas! (PHOTOS)

Happy birthday, Joe Jonas! The boybander turned solo superstar turns 22 today (Monday, Aug. 15). The teen heartthrob is all grown up!

Joe has been making the rounds promoting his debut album, traveling the world to do interviews and gleefully greeting fans while signing autographs and posing for pics.

While he’s been making headlines for his music, the Jo Bro has also been the subject of romance rumors after being spotted with a number of lady friends over the past few weeks.

He was spotted taking a mystery gal pal to dinner last week and was recently linked to model Karlie Kloss, who told Life & Style about her relationship with the heartthrob, saying, “No, we’re really not [an item]… We’re great friends, and I do love him as a person.”

Late last month, Joe was spotted making out with another hottie — on the set of his music video.

No doubt Joe’s slick wardrobe is part of his appeal. Every girl’s crazy about a sharp dressed man! To celebrate Joe’s big day, Celebuzz has compiled a gallery of some of his best suit styles. Take a look through the pics and tell us which one is your favorite in the comments!
