It's Not Even Her Birthday! Rihanna Shows Off Her Cake (PHOTOS)

Rihanna is the it-girl of the century! Recently, one of her friends, who goes by the name of Leandra, posted a surprise picture she found of Rih Rih stashed in her phone.

PHOTOS: Rihanna Releases New Album Details!

The picture is very steamy to say the least.

It features our favorite bad girl showing off her cake, cake, cake in a leopard and polka dot bikini ... AND she is doing so from the back!

We just had to show this picture off.

DETAILS: Rihanna Follows Chris Brown On Twitter... AGAIN!

It's Rihanna in a way we rarely get to see her. Check out the Bajan beauty showing off her birthday cake and let us know what you think - Is it just right, too much, or too little?
