American singer Lady Gaga returned to a massive audience for the first time in eight years to headline the Coachella Valley Music and Arts Festival on Friday night, dancing with model skeletons, fighting a dancer dressed as a monster and serving up a surprise encore.

Friday night's performance marked Lady Gaga's second time headlining Coachella, but in many ways it felt like her true first time.

Lady Gaga promised mayhem from Mayhem at Coachella - and she's ready to deliver. In her interview with Rolling Stone, the pop queen said she was excited to play her Mayhem standout "Killah" during her headlining festival set this Friday.
