Happy birthday to Jason Derulo! The singer turns 22 today, and in celebration of his birth and career, we want all of you Derulo fans to vote on your favorite song!

In 2009, Derulo broke into the world pop stardom with his hit single 'Whatcha Say,' off of his debut self-titled album. It became clear that there was a new dancing, hot R&B crooner to reckon with immediately, and he followed up the success of 'Whatcha Say,' which went to No.1 on the charts, with his uptempo single 'In My Head.' Once again, Derulo broke into the Top 10 on the charts, peaking at No. 5 with the danceable jam.

Then came 'Ridin' Solo,' an refreshing breakup anthem that was empowering instead of depressing. His next single 'What If' might not have done as well on the charts, but it was yet another testament to Derulo's vocal talents. 'The Sky's the Limit' was Jason's last single off of his first album before he unleashed his second LP 'Future History,' which boasts club bangers like 'Don't Wanna Go Home' and 'Breathing.' 'It Girl' was another hit for the Miami native -- who also just happens to be Jordin Sparks' main squeeze -- and he followed this track up with the inspiring tunes 'Fight for You' and 'Undefeated.'
