Fantasia Barrino performed an unexpected concert Friday night at the release party for her new album, Back to Me, at Las Vegas’ Rain Nightclub, People reports. The singer, who recently attempted suicide, sang four songs (including her “Bittersweet” and Prince’s “Purple Rain”) and talked to the crowd about moving forward with her career. “They thought I was finished,” Barrino told the crowd. “I was in the hospital, but now I bounce back. Don’t ever let your haters stop you. Don’t ever let them stop your destiny.”
