Chris Brown 'Dumps' Karrueche Tran, Dating Model's Sexy Friend? PHOTOS: Breezy 'Flirts, Parties' with Blair Pena, Drops Tran and Rihanna for Another Leading Lady?

MediaTakeOut.com is reporting that Chris Brown has "dumped" girlfriend Karrueche Tran... for another sexy model (who just-so-happens to be Tran's good friend)! Breezy's apparently been getting "flirty" with an aspiring model named Blair Pena. Tran recently jetted-off to Miami for some nightclub appearances... meanwhile, Pena's been hanging out with the "Fine China" crooner in LA. The evidence is all over Twitter... is something more serious going on between the two, or are they just good pals?

MTO is known to stir-up ridiculous relationship drama, but sometimes the infamous gossip webloid ends up being right... here's what MTO is saying about Brown "dumping" Tran:

So why do we speculate that [Pena's] dating Chris - well, there are just TOO MANY COINCIDENCES. First, the streets have been WHISPERING about Chris and Blair for a minute. But what really got our ears PERKED UP was when she flew into Los Angeles on Friday - the same day that Karrueche was flying to MIAMI for some club appearances. 

Breezy and Pena were hanging out A LOT over the weekend... they partied at Brown's crib and Pena even snuggled with Brown's pet pup.

@msblairr: "My new dance in the club! @Chrisbrown."

@msblairr: "I'm Jamaican mannn!!"

@msblairr: "Love this dog! X!"

And proof that Tran and Pena are friends...

Still, if fans take a closer look at Pena's Twitter, it appears she might already have a beau of her own too... 

And here's Pena's Model Mayhem page.

From Rihanna to Tran to Pena... what do readers think about Brown's ever-changing relationships status? Are Breezy and Tran still going strong despite the rumors?
