The 22-year-old singer gave a special surprise performance during the Mike WiLL Made-It & Friends concert.
Miley sang her song “23″ with Mike before going into her hit track “We Can’t Stop.”
“This is Texas,” Miley told the crowd. “I don’t know how f–king high you are, but we’re high as f–k up here.”
