But as Mstars previously reported, Breezy can't seem to forget his infamous "Diamonds" ex. He recently pulled this rather shady move on Instagram:

The 25-year-old R&B star "liked" a photo of RiRi flaunting a sexy gold bikini on Instagram. MediaTakeOut.comeven captured a screenshot of it.

Breezy quickly deleted the "like" after fans started freaking out - but why would he risk doing so! 

As fans already know, Rihanna's no longer dating rapper Drake. So, is a Chrianna reunion even possible?

Probably not.

An alleged HollywoodLife.com insider reveals that Brown only has eyes for Tran. As for "admiring" RiRi's sexy bikini bod...

"I don't know anything about that, but Rihanna isn't on his mind... [He's] focusing on the important things in his life: himself, his music and Karrueche."

How sweet! So, do Mstars fans think Breezy would ever cheat on Tran, despite their "awesome" relationship chemistry?
