Could Rihanna be pregnant with her first baby? According to Media Take Out, a source revealed that people close to Rihanna believe she's pregnant. MTO claims that it can "confirm" that the signer has stopped smoking weed and cigarettes recently and also stopped drinking.

The source told the site that Rihanna also refused to attend an after party while on tour Drake because she said there would be "too much alcohol and weed smoke." Instead the 26-year-old reportedly hung out in her hotel room.

So what other "proof" does MTO have? The gossip site also claims that Rihanna bought a decafinated tea when she photographed hanging out with her father.

"The most interesting part of this story is - assuming Rihanna is pregnant - whose baby is it? While it seems like it should be Drake's... we can tell you with 100% facts that Rihanna visited Chris Brown while he was in rehab," MTO reports, alleging that the two slept together.

While we're not so quick to believe the story, Drake and Rihanna have been spending a lot of time together and there were reports that they had finally made their relationship official. Even though Rihanna and Drake have not publicly confirmed they are together, several sources told TMZ that the two are definitely a couple.

According to the site, sources said that the "Days in the East" rapper is smitten, with one source saying that Drake is "in the best mood he's been in a long time." The source also said that the "Stay" signer is taking the romance very seriously and wants to spend as much time together as possible.

Drake has never hid his feelings about Rihanna and talked about her during a recent interview with Rolling Stone.

"She's the ultimate fantasy. I mean, I think about it. Like, 'Man that would be good.' We have fun together. She's cool and s**t. but we're just friend," he said. "That's my dog for life."
