Snapshot: So, this is how Rihanna celebrates Germany's World Cup win...

Rihanna had a blast watching the 2014 FIFA World Cup final football match between Germany and Argentina last night. During the ceremony, which took place at the Maracanã Stadium in Rio de Janeiro, Rihanna was so caught up in Germany's win that she exposed her bra to celebrate!

I'm sure folks there took the time out to appreciate Rihanna actually wearing a bra... given that Rihanna loves to let them hang loose in their multiple transparencies. Just imagine the ruckus. All in good fun, though!
