It's over! Kylie Jenner and Tyga called it quits. According to TMZ, the "Keeping Up with the Kardashians" star ended her relationship with the rapper on November 19 which coincided with his 26th birthday. She didn't attend his birthday party or wish him a happy birthday.

Their breakup was reportedly "sudden and nasty" following Kylie's return from Australia after she promoted clothing line with her sister Kendall Jenner. "It's something Tyga did," a source said. Kendall who never liked the rapper allegedly had harsh words about she was out at dinner.

"They are on a break," a different insider tells E! News. "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 herself and do her. Tyga is not giving up as that's his one and only lady." Meanwhile, a source from his circle claims "he's devastated" and denies "doing anything" at all.

Tyga was joined by his friends that included celebrities like A$AP Rocky, Wiz Khalifa, Jamie Foxx, Leonardo DiCaprio, and Christina Milian. He kicked it off at The Nice Guy in West Hollywood before heading to 1Oak nightclub.
