Kylie Jennerstarted 2020 with a new love interest -- or that's at least what the internet thought -- after the billionaire posted several flirty pics with a new dude.
Kylie brought in the new year by partying it up in WeHo with friends ... but fans were quick to notice one guy made several appearances on her Instagram page and story.
The mystery dude is Zack Bia, a 23-year-old exec and DJ from L.A. who rubs elbows with everyone from Draketo The Weeknd. Bia also dated singer Madison Beer on and off over the years.
Waiting for your permission to load the Instagram Media.
Sources connected to the two tell us Zack and Kylie are just friends and have known each other for years. Bia has deep connections at Delilah -- the backdrop for Kylie's 21st -- and other L.A. clubs, so the two have become well acquainted.
