Is Jack Antonoff officially off the market again? That's the question that arose when the record producer was spotted sitting court side with model Carlotta Kohl at the Knicks game in NYC on Saturday night. While the home team ended up defeating the Charlotte Hornets 124 to 101, all eyes were truly on Jack and Carlotta as she laid her head on his shoulder and sat close by. According to Us Weekly, the two have been dating since January, but it hasn't been confirmed by either party. Recently, Jack was rumored to be dating his musical pal, Lorde, after splitting from Lena Duhman earlier this year. As it turns out, Jack and Lorde are just friends.
