Reality TV star Kylie Jenner has split from rapper Tyga after reportedly dumping him on his birthday.

The Rack City star was photographed celebrating turning 26 on Thursday (19Nov15) with a group of pals at The Nice Guy restaurant in West Hollywood, before heading to celebrity hotspot 1OAK, where he partied with A$AP Rocky, Wiz Khalifa, Jamie Foxx and Leonardo DiCaprio.

Kylie, who had just returned from Australia, was noticeably missing from the bash and now reports suggest the couple, which began dating last year (14), is no longer together.

Sources tell TMZ.com Kim Kardashian's teenage sister called off the romance as a result of "something Tyga did".

"They are on a break," another insider reveals to Eonline.com. "They were just a week or so ago talking about 'ever after' and things got messy this past week. Kylie wants time to just be by her self and do her. Tyga is not giving up as that's his one and only lady."

Kylie has fueled the break-up rumors by failing to send Tyga a birthday message on her multiple social media platforms, where she has been flaunting the romance in recent months.

The split reports emerge just two months after the Keeping Up with the Kardashians regular dismissed speculation the pair was planning to wed, after Tyga appeared to refer to the 18 year old as his "fiancee" in a SnapChat post.

"Not planning on getting married anytime soon," she wrote on Twitter as she shut down the claims.

The stars, who made their red carpet debut together at the MTV Video Music Awards in Los Angeles in August (15), have faced much scrutiny over their relationship as Kylie was just 17, a year under the age of consent in most states, when they first got together.

They ignored the criticism and Kylie recently insisted fans will never know everything about her private life, despite sharing so much online and on TV.

"Living in the spotlight, people think they know everything about me - but they don't," she said in a video on her blog. "I've never believed in the idea of the public knowing everything about my relationship and every time I break up and make up, I'm not afraid to show who I'm dating, but I'm also not about to talk about every little detail of my relationship."
