Miley Cyrus might have been co-hosting the MuchMusic Video Awards in Toronto, Canada tonight, but that didn’t mean she’d abandon her good-time anthem “Party In The USA.”
The teen queen, dressed in skimpy street gear, opened the show with a performance of the track on an outdoor stage surrounded by thousands of fans.
As the party got underway on stage, a mystery guy on a bike rode out wearing with a hat and bandanna covering his face just as Miley sang the lyrics “and a JB song was on.” The guy took his make-shift disguise off and — OMJB! — it was Justin Bieber!
See Miley and JB party it up below.





























i have come to the conclusion that she cant sing
MILEY CYRUS WAS AWESOME!!!!!!!!!!!!!!!!!!!!! Justin’s performance was…”ok”. But Miley was awesome when she sang Can’t Be Tamed and she hit those high notes at the end of the show. But she was really good in Party in the USA when she sang “and the DJ plays my song and I feel alr-i-i-ight!” I LOVE HER!
She is great singer and great girl too
i love you milley so much call now baby girl i’m in haiti my menber is 509-36673245
I have heard her sing this song at other events but she doesn’t sound as good…but she can still sing well.
