Wiz Khalifa Performs ‘Stayin Out All Night’ on ‘Conan’ [VIDEO]

One day after his birthday (Sept. 8) and just a couple of weeks after his album scored the No. 1 spot on Billboard, Wiz Khalifa made his way over to 'Conan' to perform his recent hit, 'Stayin Out All Night.'

Dressed in ripped jeans and a long O.J. Simpson T-shirt that read "not guilty," the rapper performed the entire song with the microphone still in the mic stand, almost like a front-man of a rock group, which looked pretty cool.

Vocally, Wiz was solid, as he did a great job of going back and forth between rapping and singing, and considering there's no lip-syncing on most late-night shows, his crooning was impressive.

Just two days ago, the 27-year-old posted a photo of him and his son, Sebastian, on Instagram with the caption, "Best gift ever." Looks like his boy was the perfect birthday present this year.
