The 14-year-old singer, who first wowed judge Simon Cowell and millions of TV viewers with a cover of Duffy’s “Mercy,” recently signed a deal with Nickelodeon and Columbia Records. She made her Nick debut on Fred: The Show. This week, Crow guest stars on Big Time Rush playing an obsessed fan.

That's no coincidence casting -- Crow will join BTR and pop-singer Cody Simpson on tour starting July 5 in Ohio.
