Jacob Whitesides isn’t yet a household name, but expect that to change soon. He’s a 17-year-old phenomenon who got his start on the second season of “The X Factor,” and has continued to build a major fan base with YouTube covers and his debut EP A Piece of Me, released in June.

Now he’s taking the next step towards mainstream domination with a new single, in collaboration with former “X Factor” judge Kelly Rowland. “I Know What You Did Last Summer” is an upbeat duet, in which the two trade flirtatious bars about a romance in the past. Sure, Kelly is 34 and Jacob’s still a teen, but age ain’t nothing but a number.
