A flash mob took over The Grove in Los Angeles Saturday afternoon, paying tribute to R&B’s own Janet Jackson by replicating some of the singing legend’s most signature moves to a medley of her hits.

Check out Miss Jackson peering down on the dancers from a balcony above the crowd! Janet is set to open The 2009 American Music Awards (AMAs) in Hollywood next Sunday, Nov. 22. The hot hitmaker will perform a medley to kick off the ceremony, which sees her late brother Michael Jackson nominated in five categories.
