Bill Belichick put a ring on it — his boat, that is.

The former NFL coach is fueling rumors he’s engaged to his girlfriend, Jordon Hudson, with a striking update to his watercraft’s name.

The vessel used to be called VIII Rings in reference to Belichick’s eight Super Bowl wins in 1988, 1991, 2001, 2003, 2004, 2014, 2016 and 2018.

The boat is now named I + VIII Rings, according to photos obtained by TMZ Tuesday.

The tweak comes as Hudson, 24, is reportedly telling people she and the 73-year-old are engaged.

The New York Times reported Tuesday that the ex-cheerleader has spilled the alleged beans to “at least one” individual.

Belichick has yet to return Page Six’s request for comment.

The University of North Carolina at Chapel Hill coach has been married once before to Debby Clarke, with whom he shares daughter Amanda and sons Stephen and Brian.

He went on to date Linda Holliday after his 2006 divorce, with news breaking of their “awkward” split in 2023.

The following year, Belichick and Hudson made their May-December romance public with a dinner date — and have continued to flaunt their romance with Instagram PDA.

We hear Holliday’s Nantucket pals have now “iced out” Hudson as she attempts “to claim her stake in the social circle.”

Belichick and his much-younger partner first sparked engagement speculation in February when Hudson wore a massive sparkler on her left ring finger at the NFL Honors.

Hudson did the same during a New York City luncheon two months later.

The pair has yet to clarify when they began dating — and even went viral for refusing to answer questions about their relationship in an April interview. However, they did admit to meeting in 2021 on a flight.

In December 2024, Hudson and Belichick rang in New Year’s Eve with their “third midnights kiss.”
