Tyga's former fiancée Blac Chyna is upset with the attention American reality TV star Kylie Jenner is receiving. The 27-year-old model apparently feels she can no longer compete with the 18-year-old Keeping Up with the Kardashians star.

"Blac Chyna's hating life right now and it's all because of Kylie," a source told Hollywood Life. "Blac couldn't turn on the television this morning without seeing or hearing about Kylie and her new app and all her business projects. It's just overwhelming. She's realizing she can't compete with Kylie. She's confided in Amber [Rose], telling her she feels like throwing in the towel on her stupid feud with Kylie and suggested Amber do the same with Kim."

Rumours that Tyga and Kim Kardashian's teenaged half-sister are dating started after they were spotted at Kabuki Japanese Restaurant in Los Angeles' Woodland Hills area in October 2014. In February, during a radio interview with 92.3 AMP Radio, Tyga talked about his relationship with Jenner.

"Whether if I tell the world that I love her or I don't, it's gonna be me to dictate that, and how I want to keep my friendship and relationship with her," Tyga said. "I feel like it doesn't matter what the world thinks. If you're around somebody, and you love being around that person, that's all that matters. I don't feel like what anybody could say would change that... how I feel for her as a person... She's just a good person, she's got great energy."

"We've got a group of friends, we've been hanging out for the longest... I've been knowing her and her family for six, seven years, so it's all love there, and we're going to continue to grow," he added.

"I love her as a person... I mean, I don't think it really matters. If you love being around somebody, that's all that matters, you know? Sometimes you gotta just let that artist live their own personal life sometimes, and you gotta respect that as a fan and a spectator of what we do," Tyga continued.
