On Thursday night 18-year-old Kylie Jenner went out with her girlfriend to celebrate the launch party for Pretty Little Things in Bel Air, CA. According to Radar Online, sources say Kylie was having a great time socializing until… her 26-year-old beau Tyga pulled up on the scene. According to an attendee “…When Tyga arrived, everything completely changed. She was no longer interested in talking to anyone else. It was all about him.”

The source added, “Kylie became attached at the hip to Tyga when he arrived and it was clear that there was tension! Kylie left with Tyga long before the party ended and she did not look happy on the way out.”

Not long after, Kylie posted the above photo to her Instagram captioned, “Mr. & Mrs.” which she deleted not too long after.
