Zayn thinks Niall's a diva!

If you've heard Zayn Malik believes Niall Horan has let One Direction's fame go to his head, don't believe it. These two group mates are still best friends. Zayn did post a hilarious picture on twitter of Niall napping with his sunglasses on. "Check this diva out! Asleep with his shades on. Pfft ha!" Zayn tweeted. Zayn was totally kidding when he posted the silly pic. Niall and Zayn have an amazing friendship, and Zayn even tells BOP Niall is "the cutest" boy in 1D. Awww! We love the Ziall boys so much.
