Rihanna Pregnancy Confirmed with Baby's Father

Last night Rihannah hosted a star studded charity event at Beverly Hills in order to raise money for Rih's charity - The Clara Lionel foundation. Rihanna looked SPECTACULAR - as you can imagine - but she's not yet showing.

Anyways, MediaTakeOut.com's spies were OUT IN FORCE at the event - trying to get ANY tidbit of information into Rihanna's secret babys father from Rih's family and close friends. Everyone was VERY TIGHT LIPPED about it - Rihanna apparently is VERY UPSET that we leaked her secret (sorry bae . .. it's our job tho . . . you'll forgive us later).

So we were NOT able to get any CONCRETE information about her babys father - except that the father is 100% NOT Chris Brown or Drake.

But we did hear A RUMOR about the paternity of Rihanna's BABY. One friend of Rih's family member told us this, "I her that father is a very rich White man, a billionaire. He wants to take care of Rihanna." We can't repeat that NAME of the billionaire . . . but Chile if Rihanna carrying that seed . . . she's GOOOOOD!!!
