This weekend, the 3rd annual iHeartRadio Music Festival was held at the MGM Grand Garden Arena in Las Vegas, Nev. Many talented music artists decorated the event with their memorable showcases performing their hit songs, and Justin Timberlake, Drake and Miley Cyrus were the crowd's favorites. The concert also featured Bruno Mars, Chris Brown and Paul McCartney, among others.

Justin Timberlake held his own night's closing performance, introduced by Floyd Mayweather as "the heavyweight champion of music." His set included his major hits, "Sexyback," "My Love," "Like I Love You," as well as "Suit & Tie" and "Mirrors."

He also surprised and wowed his curious fans by premiering two tracks, "True Blood" and "Only When I Walk Away," which are from his upcoming album "The 20/20 Experience (2 or 2)," and his recently released "TKO."

Drake's enthusiastic entrance definitely hyped up the crowd: he took the stage to "Crew Love," wearing a black shirt with a close-up of Jaden Smith's face. The t-shirt captured the moment of Jaden's reaction to his performance on the MTV Video Music Award last month. The Toronto native turned up the festival and got everyone out of their seats,

"I know you've been listening to great music all day, but I came here for the party... So I don't want nobody standing around looking like this is some ambient singing. No, this isn't that tonight. If you ready to party, make some noise for me one time."

Drake performed his hit songs, "HYFR" and "The Motto" from his album "Take Care," in addition to his remix verse from Migos' "Versace," and "Started From The Bottom" and "Hold On, We're Going Home" from his album "Nothing Was The Same," his long-awaited third studio album that is coming out September 24th, just a few hours away.

And we can't forget about Miley Cyrus. Britney Spears introduced the 20-year-old pop start to the stage; the two have worked on a song that will appear on Miley Cyrus's new album, "Bangerz" on Oct. 8. Cyrus caused a stir when she appeared onstage in a very provocative outfit, wearing a white fishnet dress with high shorts and black pasties covering her breasts. She debuted her No. 1 Single "Wrecking Ball" live.

Miley Cyrus' outrageous style indeed caught more attention than her singing, and "We Can't Stop" singer has no shame, "Things I'm doing that's getting me into trouble and it's just me doing what my heart and soul is telling me what to do."
