Lady Gaga closed out the I Heart Radio Festival in Las Vegas with a raunchy 45 minute set. Gaga performed a duet with Sting, smearing fake blood on the Police legend as he pair sang "Stand By Me" and "King Of Pain". The pop megastar and spokeswoman for anti-bullying dedicated "My Hair" to Jamey Rodemeyer, a 14 year old Lady Gaga fan who committed suicide after being taunted over his sexuality.
