Steven Tyler, Jennifer Lopez, Lady Gaga - iHeartRadio Concert

perform onstage at the iHeartRadio Music Festival held at the MGM Grand Garden Arena on September 24, 2011 in Las Vegas, Nevada.

The second night of the iHeartRadio festival opened with Idol judge and legendary rocker, Steven Tyler who had an all-star lineup of guest performers join him on stage, including Jeff Beck on lead guitar.

Steven kicked off the set with “Sweet Emotion” with Sting on bass. Steven’s fellow Idol judge, Randy Jackson picked up the bass for the next number, “Feels So Good” with Nicole Scherzinger joining them on stage to share vocals.

Steven rounded out his set with a couple of covers including the Kinks “You Really Got Me” and Sly and the Family Stone’s “Thank You”.

Jennifer Lopez and a bevy of dancers came out later and performed “Get Right”, “Let’s Get Loud”, “I’m Real”, “Ain’t It Funny” and “Jenny From The Block”. Jennifer ended her set with “On the Floor”.

Lady Gaga and Sting reportedly performed long into the night, playing a set her well-known hits.
