The reviews for Britney Spears’ Planet Hollywood show are in, and it appears that the pop princes delivered the powerhouse performance she promised. The 90 minute show includes a retrospective set-list that the fans feverishly fought for, along with two new tunes off her latest record, ‘Britney Jean.’ As for her dancing, the videos indicate that she’s close to her old self. While she still appears nervous, who wouldn’t be on opening night? Give the girl a month to tighten up her choreography and acclimate to the awe-inducing venue, and I’m sure she’ll rid the kinks. Overall, one thing is clear. Britney is back! Watch Miley Cyrus lip-syncing on opening night. I’ve also included a clip from the show. Enjoy!
