Chris Brown vs. Tyga Beef, Karrueche Tran's Ex 'Jealous' Of Kylie Jenner Love? 'Do It Again' Music Video Affection Sparks Baby Mama Heartbreak

Several people disapprove of rapper Tyga's "inappropriate" relationship with 17-year-old Kylie Jenner. But despite the constant backlash, their "young love" remains strong. And rumors suggest that Trigga's good hip-hop pal Chris Brown wishes he could have the same sort of affectionate relationship with on-and-off again girlfriend, Karrueche Tran.

Breezy and the "Rack City" emcee are currently filming a new music video for Pia Mia's hit single, "Do It Again." The "Keeping Up With The Kardashians" beauty was spotted wandering around during the shoot earlier this week, in order to "keep an eye" on Trigga (who was constantly surrounded by sexy bikini-clad models). But Jenner wasn't jealous, and acted very lovey-dovey the entire time. The 26-year-old "Loyal" crooner was just a bit envious. Jenner's little flirty actions made Brown miss having a romantic partner:

"Kylie showed-up looking red hot to support Tyga. They were hugging and laughing and being themselves. She even brought him a pack of Starburst," an alleged insider for the popular gossip webloid HollywoodLife.com reveals. "Karrueche used to do little things like that for Chris just to spice up his day and show him that she loves him."

Sort of sad for the "Fine China" superstar, right?

"Chris took a second and just stood there, watching Kylie and Tyga interact between takes," the source continues. "He thinks they're truly in love and when the break was over, he told Tyga, 'Damn man, I wish I could be you right about now. Your happy and your girl reps for you. That's what's up.'"

But instead of trying to win Tran's heart back, should Breezy remained focused on current baby mama drama involving baby daughter Royalty?

Maybe Jenner could help hook Brown up with one of her friends! Now THAT would spark even more controversy! Sound-off in the comments section below, MstarsNews readers!
