Rihanna & Chris Brown 'Back Together' Scandal, Karrueche Tran Cheated? Rapper Flaunts Ex-Girlfriend's Angel Chain On Jimmy Fallon's 'Tonight Show' [PHOTO/WATCH]

Chris Brown's relationship with Karrueche Tran couldn't be better. Just look at the cute couple!

Breezy doesn't even mind that the 26-year-old fashionista passes wind in his bed... well, sort of.

But does the X crooner still have ex-girlfriend Rihanna on his mind 24/7?

According to the infamous gossip webloid MediaTakeOut.com, Brown may be seeing the "Pour It Up" beauty on the down-low, behind Tran's back.

Despite ongoing legal trouble, the 25-year-old hip-hop superstar's career is still skyrocketing. In promotion of his new album (due out September 16), Brown appeared on Jimmy Fallon's "Tonight Show" on Friday (Sept. 12). The singer performed his two new mega-hits, "Loyal" and "X" - check it out:

Notice anything odd about Breezy's wardrobe... specifically, his choice of jewelry?

The gold chain depicting an angel looks VERY similar to a piece RiRi owns...

Coincidence, or perhaps something more meaningful?

The Chrianna drama never seems to end, although they've been separated for months! But if Brown indeed wants to "move on" with Tran, why would he stir-up even more "cheating" hype by flaunting reminders of his past relationship in such a public way?

Tran has yet to comment on this latest "shade" either on Instagram or Twitter. So, stay tuned.

So - how many fans are pumped for some new Breezy music?
