Seems Chris Brown thinks he and his on-again-off-again ex-girlfriend Rihanna are cool. But based on one of her recent Instagram posts, they are anything but.

The new tiff started when Brown listed Rihanna in a Twitter post about who would be joining him for songs on his new album:

 
Rihanna, as is her way, seemingly responded on Instagram with a photo featuring a line from 'Love & Hip Hop Atlanta' star Joseline Hernandez and the accompanying caption, "Phuck O.utta H.ere B.itch!!!"

Unfortunately, while the biting commentary is amusing, it isn't 100 percent true. As you'll recall, the tempestuous twosome did do a song together for her 'Unapologetic' album. (You know, the one where they shoved their business in everyone's faces and then got mad we actually paid attention to it.)

And as recently as last month, stories circulated saying the pair had collaborated on his new record, but that after their split, he'd insisted the track be pulled. According to the scuttlebutt, Breezy's record company wanted him to reconsider, but he wasn't budging.

Now all that remains to be seen is if a Chris/Rihanna song will actually appear on the new album -- or if she'll put her lawyers where her mouth is and let them take care of it.
