Ozzfest returned to ring in New Year's at LA's Fabulous Forum on Monday, and while Ozzy headlined, the big surprise was during Rob Zombie's set – when he brought up Marilyn Manson, who had just performed, and a surprise guest that was not on the bill – Motley Crue bassist Nikki Sixx.
The all star cast of rockers broke out into a cover of The Beatles' "Helter Skelter" – a song Zombie and Manson covered in anticipation for their co-headlining tour in 2018.
