Karrueche Tran pregnant? Rumors spread that Chris Brown's former girlfriend is expecting

Chris Brown was back with his model ex girlfriend Karrueche Tran Monday - barely 24 hours after smooching with Rihanna, The Sun reports.

According to the nationalledger.com , the rumor mill is buzzing that it might be because Tran is pregnant.

According to the report, Brown and Tran were photographed together leaving Brown's Los Angeles home.

In other news, Pop star Rihanna hasn't gone on a date in two years because no one is "ballsy" enough to ask her out.

The singer has been linked to a string of eligible men and is now reportedly back in Chris Brown's arms - but she admits she has been looking for love since her 2009 break-up with her ex-boyfriend.

In a recent Vogue magazine interview - before Brown confessed he was still in love with Rihanna and broke off his romance with model Karrueche Tran - the Umbrella hitmaker said, "I have not been on a date in forever. Like two years. Haven't gone to the movies, to dinner. Zero. I would love to go on a date.

"I'm a woman. A young woman, vibrant, and I love to have fun. And I have too many v**inas (females) around me at this point.

"Seriously, all I want is a guy to take me out and make me laugh for a good hour and take my a** back home. He doesn't even have to come up. All I want is a conversation for an hour."

And the 24 year old worries her wild girl reputation puts men off: "No one asks. Trust me on that. I'm waiting for the man who's ballsy enough to deal with me. I'm going to wait, though. You always find the wrong s**t when you go looking."
