Drake Sloppy Seconds: 'Chasing' Exes Rihanna & Karrueche Tran, Jealous Chris Brown Break-Up?

Drake once indulged in a romantic fling with Rihanna, and earlier this month he was spotted "chatting-up" aspiring model Karrueche Tran at a popular Los Angeles nightclub. And what do these two Hollywood beauties still have in common? Both dated hip-hop "rival," Chris Brown! So, is Drizzy intentionally pursuing Breezy's exes in order to get a rise out of the "Loyal" crooner?

Apparently 26-year-old Brown's finally over such drama, and is rather amused by the Toronto emcee's "jealous" antics:

"Chris is glad he's able to be of service to Drake yet again! Drake's always quick to throw Chris' name around in his music," an alleged HollywoodLife.com insider explains. "And Drake's always quick to go behind Chris and pick up his exes."

Remember, the YMCMB superstar JUST blasted Brown's relationship with Tran in the hard-hitting mixtape track, "Live From The Gutter" (featuring Future):

Drizzy viciously raps, "This is for my n*ggas on that bullsh*t and that nonsense. This is for my dawgs that go Karrueche with the chopsticks." 

Ouch. But why didn't the X singer explode with another epic Instagram rant? Well, he actually pities Drizzy's failed attempts at finding love...

"The sex between Chris and his exes, like Karrueche and Rihanna, has been downright hot," the source continues. "Drake can still smell Chris' scent on Kae and Chris knows that's why Drake will be forever envious of him."

Do MstarsNews readers find this thought amusing? Drizzy never actually hooked-up with Tran, but his friendly approach was somewhat flirtatious...

So, if the 6 God hypeman discovers this is how Brown truly feels, will another crazy feud erupt between RiRi's former lovers? Stay tuned and share your thoughts in the comments section below!

Oh - and what about rumored girlfriend Serena Williams?

Meanwhile, Breezy remains focused on his highly-anticipated upcoming album dedicated to adorable daugter Royalty (scheduled for a November 27 release).
