Things are looking pretty icy in the Belichick family lately … Bill‘s daughter-in-law, Jennifer Schmitt, appeared to steer clear of his girlfriend, Jordon Hudson, at Saturday’s UNC college football game.

While the 73-year-old head coach led his North Carolina Tar Heels to a 20-15 victory over Stanford, the two women reportedly kept their distance at Chapel Hill and were not photographed interacting with one another.

Check out the pics … Jordon, 24, stood watching the game with crossed arms in the suite, wearing a white tank top and blue reptile miniskirt.

Remember … Jen bashed Jordon on Instagram earlier this year for her seemingly overbearing behavior during Bill’s now-infamous interview with CBS’ Tony Dokoupil.

Jen — who is married to Bill’s son Stephen — wrote, “Publicists act in a professional manner, and don’t ‘storm’ off set delaying an interview” … a comment which may have gotten under Hudson’s skin a bit.

Bill was adamant Jordon crossed no lines — saying in a statement she only interjected after he repeatedly told Dokoupil and “CBS Mornings” producers he solely wanted to talk about topics related to his book, “The Art Of Winning: Lessons from My Life in Football.”
