Who knew that 19-year-old rap star Desiigner was also a fan of Motown?

The "Timmy Turner" MC, who is famous for his unpredictable ad-libs, was videotaped by the folks over at Genius singing along to the Temptations' mega-hit, "My Girl," while being accompanied by an acoustic guitar. Truth be told, it's pretty great to witness.

According to a one-on-one chat with Pusha T for Interview Magazine, the Brooklynite dabbled with singing before becoming an overnight hip-hop sensation thanks to his song, "Panda."

"I used to sing to the girls, ‘Happy Birthday’ and all that," he said. "Did the Temptations. I always knew how to play around with my voice, make people laugh. I’d be crazy. Just my swag I guess. God blessed me."

Well, color us surprised by this young man's pretty decent voice!
