I'm sort of obsessed with the fact that Little Mix and One Direction are besties.

First, Little Mix opened for them at the Apple Music Festival in London and were caught backstage dancing around to the boy band, looking all sorts of adorable.

Then, One Direction got a first listen of their new single, "Love Me Like You," and couldn't help but dance and fall in love with it.

And now the girl group -- Jesy, Leigh-Anne, Perrie and Jade -- are paying tribute to the boys once again by covering their single "Drag Me Down."

The girls stopped by Capital FM to play a friendly game of Instaoke where they randomly pick which songs that they had to cover. Things started off with Little Mix putting their own spin on Ellie Goulding's "On My Mind," and then they went into a rousing rendition of The Weather Girls' "It's Raining Men" before bringing their sassiness and incredible voices to 1D.

Perrie was clearly into it, and that's not too surprising, since she picked this as her song of the summer.
