You may have watched every moment of Sunday night’s Billboard Music Awards, but you still didn’t see everything that took place.  In a near repeat of the infamous Madonna and Britney Spears kiss during the 2003 MTV Video Awards that got worldwide attention, at Sunday’s show Rihanna planted a big kiss on Britney during their duet on the song “S&M”. But just before the big moment, the director cut away to a shot of the audience.

- Those who saw it live said that while Rhianna seemed really into the kiss, Britney just lip-synced it.  

- To make up for it, the director showed Justin Bieber kiss his mom backstage.
