It's the weekend and the iHeartRadio Music Festival 2014 is going to take place in Las Vegas. If you were unable to buy tickets, you can still watch or listen. We take a look at the lineup of performers below.

Ryan Seacrest will be the host of the two-day event, which started on Friday and will end on Saturday. While it is predicted to be one huge musical extravaganza, the line-up this year will not have as many musical legends as before. As usual, it is expected that there will be first-time collaborations among several of the performers. According to Hollywood Take, Friday saw performers such as Ariana Grande and Taylor Swift take to the stage. Also in the lineup were Steve Aoki, Nicki Minaj, Usher, Coldplay, Bastille, Motley Crue and Zac Brown Band. Macy's iHeartRadio Rising Star Before You Exit will also be performing.

Saturday's show will have some heavy hitters such as Ed Sheeran, Eric Church, Calvin Harris, Weezer, Train, Iggy Azalea, 50 Cent, One Direction, Paramore and Lorde. MGM Resorts Village will host a separate event on Saturday as well. The show will feature Iggy Azalea with acts like 5 Seconds of Summer, Childish Gambino, Kacey Musgraves, Meghan Trainor and Magic!.

Programming chief Tom Poleman of iHeartMedia said that the show is all about creating an unbelievable night of music and bringing the iHeartRadio music app to life, Billboard reports. He said that at this stage of the annual festival, the artists are the ones that come to them. He also announced that Nikki Sixx will be playing with Motley Crue.

The festival starts in the evening. If you cannot be in Las Vegas, you can still listen to the show at selected Clear Channel radio stations and Yahoo will have live streaming. Highlights of the two-night show will also be shown on CW.
