The IHeartRadio festival wasn't the only big music event going down in Vegas last weekend.
Amateur DJs were flown out to Vegas to work the turntables at Marquee nightclub on Monday for their spin-off contest.
Some of the famous judges who will decide on the winner include LMFAO, Lil Jon and DJ Vice.
And I even got try out spinning for myself...
Trust me, it's not as easy as it looks!
I wasn't the only one partying in Vegas during the week. Justin Timberlake was in town to introduce Lady Gaga during IHeartRadio on Saturday night, and he's hanging in the desert all week.
The actor hit the greens today for some golfing at the Shriners Hospitals for Children Tournament today and will host his own charity concert this weekend.
Will on-again girlfriend Jessica Biel join him for that, too? Stay tuned!
