Kylie Jenner & Tyga Split For Good: She Is 'Done With His Lies!'

Keeping up with the Kardashians superstar Kylie Jenner has finally pulled the plug on her tumultuous relationship with rapper Tyga.

RadarOnline.com has exclusively learned that the 18-year-old plastic princess broke up with the 26-year-old rapper for the most recent time several weeks ago. But after giving him a change to redeem himself over the past few weeks, she finally gave up.

According to a source close to the former couple, "His last chance is over!"

"She is sick of his lies," the insider said. "He has f*****d up one too many times and Kylie just feels like she needs to move on with her life."

Although the couple have been off and on for more than a year now, the source told RadarOnline.com that the final blow came when Jenner's older brother, Rob Kardashian, 29, proposed to Blac Chyna, 27. As fans of the show know, Blac Chyna is also the baby mama to Tyga's four-year-old son, King Cairo.

After the sudden proposal, Tyga published a Twitter rant showing his support for his former lady love's new romance. And as RadarOnline.com reported, Jenner was livid.

"Kylie was beyond p*****d off when Tyga opened up his big mouth, because she instructed him not to say a word and he went against her wishes," the source added.

And that was the last straw for the troubled couple.

As RadarOnline.com reported, Tyga has been accused of cheating on Jenner  several times with many women, including several lesser known models and even a transsexual.
