[artist id="501686"]Britney Spears[/artist] flirted with fans on [article id="1655570"]"Hold It Against Me,"[/article] threw a party with [article id="1661233"]"Till the World Ends"[/article] and got a bit cheeky on [article id="1663589"]"I Wanna Go."[/article] Now the singer is wondering what her fourth Femme Fatale single should be. She even recently posted a poll on her Facebook page pondering whether her next single should be "Criminal," "Inside Out" or "(Drop Dead) Beautiful."

The Internet has been abuzz about what that next single could be, and Spears' "(Drop Dead) Beautiful" collaborator Sabi says that she's just as anxious to find out what the decision is as well. "I don't know, I don't know, it's all up in the air," she explained to us backstage at the [article id="1668717"]Femme Fatale Tour[/article]. "Nothing is for sure yet. We'll see. It would be really nice if that were the next single. The crowd seems to really love it when we do it in the set. That's kind of like how we've been checking it out."

The videos off Femme Fatale have been as unique as the singles selected, with Spears playing a resurrected pop star ([article id="1658275"]"HIAM"[/article]), a sweaty party queen ([article id="1661401"]"Till the World Ends"[/article]) and a paparazzi-stalked pop star ([article id="1666219"]"I Wanna Go"[/article]). Sabi said she would love for the "(Drop Dead) Beautiful" video to mirror the setup she and Brit use during their tour performances of the song.

"What we do onstage is very Egyptian, Middle Eastern-like feel and a lot of vanity kind of stuff," she said of the performance, which features lots of mirrors and sparkles. "So I would just imagine what we kind of did for the green screen, where there's mirrors and there's boys that are like oiled up ... I would imagine us in goddess-looking outfits and us looking vain," she added.
