On Sept. 28, Jason Derulo hit the streets of New York City to perform some of his hits with the New York Knicks dance team. The performance took place outside of Fuse Studios in New York City, right near Madison Square Garden, which is home to the Knicks and their troupe of beautiful and fit dancers.

Derulo tweeted about the flash mob yesterday, writing, "NYC, what r u doin today at 4pm? Come hang out w/ me #JasonDeruloFlashMobMSG." Although it wasn't really a true flash mob, since Knicks dancers don't really look like random commoners, it was still an entertaining impromptu show. Derulo performed older hits like 'In My Head' as well as new songs like 'It Girl' off of his brand-new LP, 'Future History,' which dropped on Tuesday, Sept. 27. Derulo danced with the Knicks girls, who wore spandex body suits in their team colors, as he spoke to crowd gathered outside to watch him perform. Even though the sound wasn't as loud as he would've liked, you could tell Derulo was very excited to be singing and dancing for his fans.
