The Hannah Montana father-daughter duo shared the stage with Hollywood's beloved glam rock cover group, Steel Panther.
Miley and Billy Ray Cyrus joined the hilarious hair band at Los Angeles' House of Blues to perform Def Leppard's hit, "Pour Some Sugar on Me."
Billy Ray, 53, fit right in with the glam rockers as he donned a leather jacket, sunglasses, long hair and a Steven Tyler-esque scarf.
Miley really used all of the stage space -- dancing and singing around the musicians and using their props. Donning a skimpy black jumper and thigh-high boots, the "We Can't Stop" singer jokingly looked at herself in a mirror during the performance, and later grabbed a scarf and sunglasses.
In addition to the Steel Panther performance, Billy Ray has hinted to ET about another collaboration between his 22-year-old daughter and a breakout reality star. The country crooner chimed on rumors that Miley might be teaming up with Caitlyn Jenner on a project.
"She's always getting into something new," Billy Ray said of his daughter’s Instagram post that hinted at a "Call Me Caitlyn"-themed collabo involving her Happy Hippie Foundation. "I wouldn’t be surprised at all."
