2 Chainz And Kanye West Enjoy Cake In 'Birthday Song' Video

Yeezy joins Chainz in 'trippy,' booty-shaking, Andreas Nilsson-directed clip.

2 Chainz enlisted the help of Kanye West's director Andreas Nilsson to put together his "Birthday Song" video, and even to the untrained eye it's easy to see that the Atlanta rapper and his eccentric director combined their ideas to make a complete product.

During a recent visit to "RapFix Live" 2 Chainz admitted that he and Nilsson initially had very different concepts for the video, but they collaborated to make it work. The birthday celebration begins in 2 Chainz's crib, with family and a birthday cake in the shape of a butt with candles on it, which we're inclined to credit to 2 Chainz. His backyard and the block party outside are not out of the ordinary, filled with well-endowed woman (refer to the song's hook for an accurate description) who enjoy trailing Kanye West, but the creepy clown who eventually gets assaulted and the random contortionist on the sidewalk seem more like Nilsson's kind of thing.

"It's very trippy," 2 Chainz said of the clip. "I actually let Kanye's director shoot it ... and we were on the phone going over the treatment. I was just being conceptual. It's called 'Birthday Song,' so what do you think [of]? I think cake, balloons, candles, normal birthday stuff, but this guy just goes up the street, turns left and just keeps going left. He's telling me something like, 'I think it'd be nice if we put a cupcake on a girl's butt and shoot it off in fast motion, then blow up the cupcake.' So I said, 'Bro, come back home, come back!' "

"Trippy" is an accurate description of the video, which blends some standard elements of a hip-hop video with oddball visuals that make it out of the ordinary.

2 Chainz dropped his debut album Based on a T.R.U. Story on August 14.
