Rihanna won't officially turn 24 until Monday Feb. 20th, but that didn't stop her from getting the celebration started a little early.

Plenty of people turn their birthday into a week long celebration, but when you are one of the most popular women on the planet, it's going to draw some attention.

PEOPLE reports that about 100 of RiRi’s friends and family came out to celebrate with her, including her BFF Katy Perry.

The big rumor around the party though, is that Chris Brown was in attendance!

The tabloid Daily Mirror quoted a tweet from a reported guest, Katis C.:   "All I can say, CB was invited and Rihanna was acting like the happiest girl on her birthday and probably got what she asked for".

I'm sure this won't be the last we hear about a huge Rihanna birthday party, and as we all know, wherever she goes the Chris Brown rumors are sure to follow.
