Chris Brown & Amber Rose Instagram Flirt Amid Karrueche Tran Break-Up, Over Rihanna? Sexy Twerking 'Hook-Up' Sparks Raunchy Boyfriend/Girlfriend Post

Now that Chris Brown is a single man again, the "Loyal" crooner's getting a little frisky! And apparently, some fans do not approve...

Earlier this month, Breezy was spotted at a popular LA nightclub "getting dirty on the dance floor" with Wiz Khalifa's ex-wife, Amber Rose. The popular Hollywood socialite is infamously known for her sexy twerk moves, so perhaps the 25-year-old hip-hop crooner was just having some fun during an "innocent" (yet wild) night out?

But maybe something more serious is going on... the sexual chemistry is pretty evident...

The X rapper is no longer dating on-and-off again girlfriend Karrueche Tran, although rumors suggest that Breezy is "sad" and not looking forward to spending the holidays alone. But if Rihanna's ex hopes to win back his former sweetheart, he probably shouldn't post such vulgar messages on Instagram...

But the "Fine China" singer isn't involved in a boyfriend-girlfriend relationship right now, right? So why share such a raunchy text message exchange?

The photo was later deleted - several fans were not amused... one follower even commented (via HollywoodLife.com):

"well you @chrisbrownofficial can teach us thing or two how to treat women, m?"

Is this Brown's attempt at "flirting" with Rose (or Tran)? And if so, do MstarsNews readers think it works?

Well, looks like the aspiring model continues ignoring her ex-beau. She's having some holiday fun of her own (with friends):

karrueche: "Such a fun time tonight! Thank you @aventinehollywood @jttorregiani and @sylvainbitton for having us! We had so much fun! Merry XMas!"
 

karrueche: "Cheers." 

Maybe Brown's just jealous, and acting-out in his own (cyber) way?

Meanwhile, Rose remains mum about dating rumors. She's having too much fun on her own Instagram...

 Kiss it.
