Fleur East, the second-place finisher of X Factor's eleventh season, just delivered convincing evidence that she was most definitely robbed.

On last night's (November 8) episode, East, who also competed on the show's second season as part of a group in 2005, returned for a performance of her new single "Sax" that gave the show's current contestants something to aspire to. Featuring high-octane choreography, razor-sharp vocals and...a back flip?...she drew thunderous applause from the crowd, and a flurry of well-deserved, congratulatory tweets. Is this, perhaps, the second coming of Beyonce? Don't rule it out...

"@FleurEast Your performance was amazing! The energy was incredible!" Alesha Dixon shared with her followers, while Simon Cowell, who mentored East while she was on the show, posted: "How incredible was that Fleur performance tonight. One of the best I have ever seen." Coming from a man who could take issue with a young children's choir, that's certainly some high praise.

On Season 11 of X Factor, East was named runner-up to Ben Haenow, who recently released "Second Hand Heart" featuring Kelly Clarkson. She sang "All About That Bass," "Lady Marmalade" and "Thriller," among others before the show's finale last December.
