Malcolm Kelley and Tony Oller first met as costars on the Nickelodeon series Gigantic, and it wasn't long before the onscreen best friends struck up a creative collaboration behind the scenes. The pair joined forces to form MKTO, a musical duo blending pop and hip-hop. Their first single, "Thank You," cracked the Billboard Top 40 and made a splash around the world. The pair stopped by POPSUGAR Live! to perform an acoustic version of the track as they put the finishing touches on their debut album, which is due out on Columbia Records soon.
