Rihanna and Chris Brown may have shared more than victories last night (Sept. 6). The pair were snapped smooching at the 2012 MTV Video Music Awards -- likely when they didn't think anyone was watching. Problem is, when you're Rihanna and Chris Brown, the whole world is always watching.

The two VMA winners, RiRi for Video of the Year and Breezy for Best Male Video, were outed by a Twitter user who took a quick screenshot of the show on UStream. Apparently at some point during the show, the newly shorn singer and her newly powder-blue haired former flame shared a smooch. Whether it was a romantic kiss or just a greeting is anyone's guess, because Brown is still supposedly dating Karrueche Tran (though it allegedly hasn't stopped him and Rih from hooking up before), and Rihanna's been posting a lot of cryptic tweets seemingly about moving on.

Rumors about the pair had been relatively quiet as of late, save for Rihanna's interview on 'Oprah: The Next Chapter' in which she revealed she still loves Brown and a rumored rendezvous in St. Tropez that Brown denied. Brown himself has been keeping a pretty low profile following the nightclub brawl between his and Drake's crews, which was whispered loudly to have been over Rihanna. Most recently, Rihanna's been linked with Rob Kardashian, who was dating Rita Ora.

Considering the controversy that erupted when the pair collaborated on Rihanna's 'Birthday Cake' and Brown's 'Turn Up the Music' remixes, we can only imagine what would happen if they were to publicly reunite as a couple. Do you think they're back together? Tell us in the comments!
