“No one is supposed to know because Ty has a girlfriend,” MediaTakeOut alleges. “But he and Kylie have been low-key seeing each other for a while. They were in the VIP area where no cameras were allowed.”

Kylie and Scott.

The 31-year-old musician wasn't the only surprise guest. Kylie also hung out with sister Kourtney Kardashian's ex, Scott Disick, 32.

While Tyga has yet to comment on this newest development, he did reveal how he's doing following the breakup.

"I'm good, you know? Just another day and working hard and trying to get to that next level and achieve big things and evolve," he told E! News while promoting his clothing collaboration with Marcelo Burlon on Thursday.
