It's bad quality, but Kelly joined Maroon 5 on stage last night and performed Moves Like Jagger with them. She came on with all her male band-mates dressed as women Lord knows why.
Anyway see her kill it below! She comes on @ 2:10ish
Has X even sang this live? Oh she did... Sorry but comparing the 2 live it's no question Kelly still has the ability to deliver live and Xtine's voice is tired. Where's a HQ vid of Queen Kellz?
