This year's iHeartRadio Music Festival came to a close on Saturday night, with grand performances from Taylor Swift, Aerosmith and EDM master Deadmau5.

Swift, 22, rocked out with the MGM Grand crowd in Las Vegas, performing her new single “We Are Never Ever Getting Back Together.” The singer also had a quick outfit change during her set (both were sparkly numbers).

Pink, who made a guest appearance the day before onstage with No Doubt, delivered her own set on Saturday, singing songs from her new album The Truth About Love.

Day two of iHeartRadio brought out a slew of famous music fans, including Shane West, Kat Von D., Maria Menounos and Mamie Gummer.

The day before, Korean sensation Psy kicked around with Usher before performing onstage. Britney Spears, Demi Lovato and Ryan Lochte were also on hand for the event.
