MediaTakeOut swears Rihanna is pregnant!

MTO is so sure about this story that they bet $10k on it. Lol. Read their report below...

MediaTakeOut.com just received a blockbuster report yesterday - Rihanna is pregnant. This is not rumors y'all . . . it's 100% certificate

We spoke with two separate sources that told us that Rihanna is working on a new song on her albumM - where she will talk about being pregnant. One tipster explained, "The song is a ballad, where Rihanna talks about the "baby growing inside me."

And there's more. Rihanna has banned ALL WEED SMOKING inside the studio while she records - a VERY unusual step for Rihanna, who is known for smoking weed like a CHIMNEY!!

We're told that Rihanna is EXTREMELY happy about having a baby, and that she JUST FOUND OUT about her pregnancy a FEW DAYS AGO!! Congratulations to Rih - we LOVE HER TO DEATH and are so HAPPY about her new family.

As for the father - we have NO IDEA WHO IT CAN BE - some folks are speculating that it could be Drake. But we don't have ANY INFORMATION on who it can be.

Oh and we are not 80% sure about this, or 90% . . . we're 100% ON RIH BEING PREGNANT. In fact, we're SO CERTAIN . . . that we'll bet ANY MEDIA COMPANY that doubts Rihanna's pregnancy $10,000. Come on . . . anyone wanna put their MONEY UP against our reporting!!!
