Music has taken over Las Vegas this weekend thanks to the inaugural iHeartRadio Festival.
Fans flocked out to the MGM Grand in Sin City to see The Black Eyed Peas, Bruno Mars, Coldplay, Alicia Keys, Jay-Z and Jane's Addiction -- just to name a few of the performers -- on the first night of the two-day music festival.
And if you think those acts are good, just wait. Jennifer Lopez, Steven Tyler and Lady Gaga are also set to take the stage before the festival closes Saturday.
Ryan Seacrest and Clear Channel Radio are the masterminds behind the first-ever music fest, which was announced over the summer.
"This is a once in a generation gathering of artists and fans from all over the country for a true, must-see music event," said Seacrest at the time of the announcement.
