As if having one superstar involved in this epic tune isn't enough, Gaga decided to pull some strings and add another -- the one and only Beyonce Knowles.

Over a mix of deep, fuzzy synthesizers, chiming strings and crashing percussion, Gaga and Bey sing to their annoying significant others about laying off the phone calls when they're out with their girls. Don't bother these ladies when they're out at the club sipping their bub, because they ain't gonna answer!

The stutter-singing in the chorus of 'Telephone' and the fast-paced "Call all you want, but there's no one home" hook are wildly catchy. And just like Gaga, we want no interruptions while we're busting our butts grooving to this energetic, earworm of a tune.
