Rihanna will shine bright like a diamond in December, as she has been confirmed as a performer at the 2012 Victoria's Secret Fashion Show.

The glorious event, featuring the company's extra beautiful models aka Angels, will air on December 4 at 10PM (9PM CST) on CBS, per a Facebook post. So make a note in your calendars now, members of the Rihanna Navy, especially those of the male persuasion, since this is one performance you do not want to miss.

Rihanna is set to perform two songs, including her brand new single 'Diamonds' from her forthcoming seventh disc. Two other musical acts are slated to perform; those have yet to be announced, reports The Huffington Post.

This news leaves us with two very important questions. What will RiRi wear? Rihanna is known for her skimpy, lingerie-like attire, and she is extremely comfortable letting it all hang out, so having her perform at this particular event is particularly fitting. We're expecting her to show some skin and dress provocatively. She won't allow a pack of gorgeous undies models to upstage her, that's for sure.

And the second question is: Will diamonds factor into her attire? Will she wear a diamond encrusted bra and thong, made especially for her by Victoria's Secret? It's entirely possible, given the singer's penchant for showing off her assets and beyond.

Incorporating diamonds into the mix is an effective promotional tool, too. You can bet we'll be watching.
