Joined by numerous Hip-Hop legends, Eminem certainly brought an exciting performance at the launch party of Dr. Dre and Jimmy Iovine's Beats Music streaming service at Los Angeles' Belasco Theater over the weekend.
Sia was featured on "Beautiful Pain," a track off Eminem's recently released "The Marshall Mathers LP 2." The singer has agreed to donate the proceeds she received from the collaboration to the Los Angeles Gay & Lesbian Center, which serves homeless LGBT youth.
