Joe Jonas arrives at Haze Nightclub on Saturday night (August 13) at Aria in Las Vegas.

The 21-year-old musician (in head to toe A|X Armani Exchange) hit the black carpet before heading inside where he performed tracks from his solo album, FastLife!

Earlier in the week, Joe grabbed a yummy bite to eat at Susan Feniger’s Street in Hollywood with a gal pal.

In case you missed it, listen to Joe‘s latest song, “Love Slayer.” Tell JJJ, what did you think of the new track?
