Bill Belichick's relationship with Jordon Hudson appears to be going from strength to strength, and the 24-year-old cheerleader has now revealed her pet nickname for the new UNC coach.
Belichick, so long known as a hard-nosed, no-nonsense football man, appears to be showing his softer side with his new romance, accompanying Hudson to various glitzy events.
Earlier this month, the pair were in New York City for a night at the American Museum of Natural History, and in a post about the event, Hudson appeared to let slip what she calls her man.
'December 6th was more than just an incredible "Night at the Museum". The evening was saturated with all of my favorite things: friendship, education, philanthropy, glamour, beet salad, Billy, dance-worthy music, ornithological & oceanic exhibits.
'We created so many great memories together while supporting a great cause; my heart is filled to the brim!!!'
Belichick has not been known as 'Billy' publicly by any of his players in the past, preferring to go by 'Coach' or - to friends - just 'Bill'.

Hudson, it appears, has broken through his tough exterior, and is letting the world know about it.
Alongside the caption and nickname reveal was a series of photos from their glamorous night in the Big Apple, including a loved-up selfie from inside the museum.
They also posed with friends on the red carpet, and Belichick was beaming alongside his girlfriend as he dressed up in a tuxedo and bow-tie.
It has been a whirlwind few weeks for the New England Patriots icon, after he swapped the NFL for his first coaching job in the college game.
Belichick will be head coach of North Carolina next season, and the 72-year-old has inked a five-year deal with the program.

In his first week in the role, he was already hard at work in the transfer portal, making former Holy Cross offensive lineman Christo Kelly his first new arrival.
'We've been talking to a number of players and we have more coming in this week as part of the portal, that closes on Sunday, so we've got guys coming in pretty much every day this week,' Belichick said on ESPN's The Pat McAfee Show.
'We're selling the program but, quite honestly, we've had a lot of players and agents are coming to us saying that "We wanna be part of the program".'
Despite criticism and skepticism over Belichick's foray into collegiate football, the former NFL coach appears to be embracing the process.
'It's fun, and it's great to be at North Carolina, and great to be at this great university and back in the game. We're spending money, not as much as we spent in the NFL,' Belichick continued.

'It's a new landscape in college football, but honestly not too different—it's different, but this part of the process isn't too different from what we've dealt with in the NFL.'
Belichick had been out of work since calling time on his legendary 24-year reign as Patriots head coach at the start of the year and failing to land a top gig elsewhere around the NFL.
Belichick and UNC's five-year deal is worth $50million, making him one of the highest-paid college coaches on an annual salary basis.
His pay is also a massive jump from the $5m salary UNC paid Mack Brown in his final season in charge of the program.
