In the footage, Jackson can be seen laying a big kiss on her -- before everyone eventually left the screen and the camera cut off.

No word if everyone was just having fun -- or if this is the start of a new relationship for Jackson. But, either way, it's been a notable past few days for the younger Mahomes.

He was just Patrick's best man at the Chiefs star's wedding in Hawaii last weekend, and his social media presence has ballooned even further following Patrick's big day.

Jackson now has over 1 million followers on TikTok -- and it's clear, dude has become a huge star in the social media world.
