Hip-hop star Tyga is letting it be known he's too focused on his relationship with girlfriend Kylie Jenner to care in the least bit about ex Blac Chyna now taking up with rap rival Future.

TMZ reports there were some rumblings that the two rap stars were well on their way to becoming enemies after it was recently revealed Chyna and Future are now hooking up, and she even got a tattoo of his name etched across her wrist.

But sources close to the "Rack City" rapper insist he gives "zero f**ks" about his ex and his former partner on the hit song "Show You" now spending time together. Instead, the source added he's about Kylie, and making things work with the 18-year-old reality TV star.

Meanwhile, Future is rumored to think Chyna now sporting his name for all to see is "dope," despite things still being so early in their month long relationship. Word is he sees it as a sign of commitment and an expression of how deep their connection extends.

Sources add Chyna actually had the tat done nearly three weeks ago, when she and the rapper were out and about together, and he stopped to have one of his own done. Given her "it's my body and I can do what I want with it" motto, Chyna is said to have absolutely no regrets about her spur of the moment actions.

After a rumored rough patch, which included widespread rumors of each of them being unfaithful to the other, Tyga and Kylie seem to have rebounded and put things back on track.

The two were recently spotted draped all over one another and "kissing nonstop" while attending a New York Fashion Week event.

"Kylie and Tyga were kissing throughout the night," a source said. "He had his hood up, but they shared many prolonged kisses. They were totally comfortable packing on the PDA -- they looked hot and heavy and didn't have a care in the world."
