Rihanna Not Pregnant, Reps Insist

Rihanna, the 25-year-old singer, has been the subject of pregnancy rumors after cancelling four shows on her Diamonds tour, but the entertainer's representatives are denying the claims.

Rihanna canceled a show in Boston on March 10, Baltimore on March 12, Houston on April 15 Houston and most recently Dallas on April 16. Although Rihanna has been vocal about reuniting with her singer-songwriter boyfriend Chris Brown, 23, sources close to the singer are denying that the pair are expecting their first child.

Sources close to Rihanna reportedly told E! News that the singer is not pregnant, just sick. A HollywoodLife.com source echoed the same singer.

"[Rihanna] is just sick, and that's really it," the source reportedly told HollywoodLife.com. "I know, that's not a good enough reason because everybody wants some drama and the rumors that she's pregnant to make the rounds, but sorry, not this time. She's not pregnant!"

The source spoke about Rihanna being upset that she had to cancel tours on her show.

"One thing [Rihanna] hates the most is not being on stage," the source told Hollywoodlife.com. "That's where she belongs, and she knew that … since she was a kid. So you better believe that this sickness … is killing her in more ways than one."

The singer took to Instagram to confirm her disappointment having to cancel shows.

"I was sick since San Diego! I kept working because I thought two days off after the Vegas show would be enough time to recover and I (expletive) up, those were two days off from hell and today is not different!" Rihanna wrote on Instagram. "I'm sad and disappointed about it! I had all kinds of plans for Houston!"

Rihanna revealed how she handles rumors in a previous V Magazine interview.

"I don't read it anymore," she told V magazine. "I already have too many voices in my head right now! I don't have room for that other stuff."

The singer said that she chooses to tune out the negative reports so that she can focus on other things in her life.

"If I let that other stuff in, it'll take the space of productive (expletive), and that isn't good," Rihanna told V Magazine.
