Check out a preview of Saturday's new episode of "Big Time Rush."
In "Big Time Single," the guys realize Kendall – Jo = an all-time low. Now that Kendall's single, it's going to take his three best friends and one "Big Time Single" to help mend his broken heart. Will the boys be able to peel Kendall off the couch and get him in the studio to record the summer's biggest hit... or will they have to record "If I Ruled the World" without him?
You can also get BTR's new single "If I Ruled the World" featuring Iyaz on iTunes here.
Make sure to tune in Saturday at 8:00 p.m. (ET/PT) on Nickelodeon.
