Chris Brown Disses Rihanna on Twitter as RiRi Posts Sexy, Racy Instagram PHOTO from Crop Over Festival 2013: Karrueche Tran 'Friendship, Love' Stronger?

So maybe this tweet recently sent out by Chris Brown isn't referencing ex-girlfriend, Rihanna:

‏@chrisbrown: "How do u build a house without a foundation???? Friendship brings the trust and love stronger. U have to like a person to love them!"

But then again, maybe it is.

Following their erratic on-and-off again relationship, Breezy romanced former fling, Karrueche Tran. Things seem to be going pretty well between the couple - maybe because Breezy has a stronger friendship with the stunning model than he ever did with RiRi? Therefore, his love for Tran's stronger...

Whatever the case, the "Diamonds" songstress doesn't seem bothered by it. She's currently in her native Barbados, partying it up for Crop Over Fest 2013. Check out her sexy (and rather racy) festival attire:

badgalriri: "#CROPOVER2013."

Woah! Those jewels aren't covering up much, are they RiRi!

But are Rihanna's hard-partying ways getting a little TOO out of control?

Maybe Breezy just couldn't keep up with the wild-and-crazy R&B princess.
