Things are officially over between Kylie Jenner and boyfriend Tyga, according to a new report.

Sources say the 18-year-old and her 26-year-old beau split just before the Met Gala on May 2. The news comes less than a week after Rob Kardashian announced that he and the rapper's ex, Blac Chyna, are expecting their first child together.

TMZ reports that Tyga was spotted taking a model to his Mother's Day brunch, though he's not telling friends whether or not she's his new girlfriend.

Though the duo have called it quits before during their year-and-a-half relationship, there's no hope for a reconciliation this time, the site states.

Kylie has since retreated to her old room in mom Kris Jenner's Calabasas home, and seemed to address the breakup in a new Snapchat video, saying, "I'm kind of playing the mind over matter game. If you don't think it, it can't happen."
