Bad Gal RiRi is back in a bikini and we love it!

The Bajan beauty and her BFF Melissa posted a few shots from the pool the other day, and this was BEFORE the ladies got down and dirty at the Foreday Morning Jump Up party in Barbados on Saturday. Talk about the calm before the storm!

So what exactly is the Foreday Morning Jump Up party? Apparently it's an excuse to get your drink on while getting splattered with paint. Rihanna was photographed walking around with a squirt gun and water bottles filled with paint, and not only was she nailing fellow attendees, but by the end of the day she was covered in red, yellow and purple goo as well. Of course, she still managed to look magnificent -- and she had a huge smile on her face!
