Bill Belichick‘s girlfriend isn’t taking any crap about her relationship with the famed coach … calling out an online critic who tried to clown her about their romance.

Jordon Hudson posted a back and forth from her Instagram DMs to social media … showing the hate a woman — who goes by Abby Riley on the site — threw at her about her romance with the 72-year-old coach.

In it, Abby asks her if she realizes her relationship is insane … and, JH claps back by asking her if she realizes back that messaging a stranger “with the intent of harassing them with regard to their own personal relationships is insane, right?”

As you know … Bill and Jordon’s romance has received a lot of scrutiny since we broke the story about it last summer given the nearly 50-year age gap between the two.

However, the lovebirds clearly don’t care about what everyone else thinks … ’cause they’ve spent a lot of time together over the months — including spending a sweet anniversary dinner together just last weekend.

BB’s got a new job as head of the University of North Carolina football program … and, Hudson’s been hanging around the facility, sharing a pic of the field recently.
