Interestingly enough, Chyna’s own supporters seem to believe the Kardashians are to blame for the breakup, or just Kylie Jenner alone. According to multiple reports, for the last few months, Tyga has been getting very close to Kylie and Kendall Jenner. But whispers are suggesting that it is Tyga’s very close “friendship” with 17-year-old Kylie that made Blac Chyna very uncomfortable. Tyga was even the one who threw Kylie her birthday bash recently too.

Even Chyna’s own fans have been tweeting her and telling her they believe Tyga and Kylie have a budding romance and Chyna hasn’t been spotted with Kim Kardashian in a while either.

Tyga rang in his 26th birthday on Thursday,(November 19th 2015) and fans everywhere noticed that Kylie Jenner was nowhere to be found—not on social media, not at his birthday party and not by his side.

Turns out, E! News can confirm the couple—who started dating in September 2014—has broken up.

Kylie was the one who made the decision to call things off just as she returned from Australia on Thursday because of "something Tyga did," a source tells TMZ.

"They are on a break," another insider tells us. "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."

Insiders connected with the rapper also tell us that "he's devastated" and denies "doing anything" at all.

To prove the breakup even more, we must point out that Tyga celebrated his birthday with a dinner at The Nice Guy in West Hollywood before moving the party to 1Oak nightclub. Everyone from A$AP Rocky, Wiz Khalifa, Jamie Foxx and Leonardo DiCaprio were in attendance, but not one Kardashian or Jenner showed up.

Moreover, Kylie—the queen of social media—didn't mention anything about Tyga's birthday across any of her social platforms. Her most recent post is a photo of herself.

On Snapchat she also shared a video singing Bryson Tiller's "Been That Way," which features lyrics about a breakup: "She don't never want to see us go through round two/Cut her off that's what I'm doing now, you/Told me I should go out and do my thing/Damn right I do my thing."

It's also interesting to note that Kendall Jenner—who TMZ says had harsh words to say about the rapper while out to dinner on Thursday night—took to Instagram to share a photo of someone's middle finger. Perhaps a message to the rapper?

Kylie Jenner's recent appearance on The Ellen DeGeneres Show turned awkward fast, when the 57-year-old host brought up Kylie's on-again, off-again relationship with rapper Tyga.

The 18-year-old reality star split with Tyga before his 26th birthday last Thursday and was a no show at his Los Angeles birthday bash. But the controversial couple got back together before the weekend was over.

To say Kylie was hesitant to talk about her beau is an understatement.

"Honestly, people have it all wrong," she says when Ellen asks her to clear up all the reports. "We're not broken up."

Kylie refuses to even call Tyga her boyfriend, although the evidence is pretty obvious.

"We just, honestly, we became best friends before anything happened, so I think that that's awesome," she says. "And we're just, like, hanging out all the time."

"We're still together," she adds.

Kylie recently belatedly celebrated Tyga's birthday, posting a Snapchat video on Tuesday of herself and her mother, Kris Jenner, with the rapper before he blows out the candles on a birthday cake. The two also made it clear they were still an item on Sunday night at the American Music Awards, which they left hand-in-hand.

Kylie opened up about her love life in a candid post on her website and app, calling herself a "relationship girl."

"I've never believed in the idea of casual dating or being with two people at once," she wrote. "I feel like I only have room for one person in my heart and I want to give whoever I'm with all the attention they deserve."

"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," she added. "Living in the spotlight, people think they know everything about me, but they don't. I've never believed in the idea of the public knowing everything about my relationship and every time I break up and make up."
