Miley Cyrus, Bill Ray Cyrus

Last night was the historic House of Blue's final performance and it was surely an evening to remember!

Miley Cyrus closed out the night and surprised fans with an impromptu performance of Def Leppard's " Pour Some Sugar On Me" after she was called up on stage by none other than her dad Billy Ray Cyrus (who was performing alongside Steel Panther).

The famous father-daughter duo appeared to have a blast on stage as they danced around with the glam metal band as the crowd went wild, understandably. Billy Ray was seen strumming an air guitar while his former Disney darling daughter showed off some of her killer dance moves.

Meanwhile, during the star-studded night, 'N Sync's Joey Fatone was also there to help bid farewell to the legendary venue.

The former boy bander got up on stage and sang with Steel Panther during, what else, Backstreet Boys' "I Want It That Way." Awkward, much?

We wonder if the Backstreet Boys got wind of his performance!
