Lady Gaga performed at the iHeartRadio Music Fest in Las Vegas over the weekend with a stunning 1 hour performance.

Gaga performed her chart topping singles Bad Romance, Just Dance, The Edge of Glory, Born This Way, Poker Face and more.

But during her performance, the singer took a moment to dedicate her song Hair to 14-year-old Jamey Rodemeyer who unfortunately took his life last week because he was being bullied about his sexuality.

“We lost a little monster this week and I’d like to dedicate this song to him,” Gaga said.

A video montage with a photo of the late teenager played as Gaga proclaimed, “Tonight, Jamey I know you’re up there and looking at us. Bullying is for losers. Put your hands up for Jamey!”

After the touching performance, the Lady finished the rest of her set in full Gaga-ness, complete with fake blood, motorcycles and craziness.

She was even joined by guest performer, Sting, who sang a duet of the classic Stand By Me!

“Sting is one of my favorite people in the whole world because when I started in this business, I started to meet real legends but they’re not always very nice. Sting is one of the kindest, most loving people I’ve ever met,” she revealed.

Gaga was the last act and closed the two-day music fest which included performers Nicki Minaj, Coldplay, Jennifer Lopez and more.
