But Bill Belichick’s beautiful, charitable, and supportive girlfriend is the proof that Bill is a wonderful man.

Linda Holliday has been in the picture so long that most people think she is Bill Belichick’s wife.

Boston tabloids have suggested on more than one occasion that the two may be engaged, though we raise an eyebrow at that declaration.

Bill Belichick’s girlfriend proudly defines herself as “Girlfriend,” on her Instagram bio.

According to the gossip section of the Boston Herald, Linda toed the Belichick line in terms of not sharing secrets with the media, offering only semi denials when asked about the ring.

The ring also magically moved from her left hand to her right later in the evening when people began staring at the new ring.

And according to her website, the designer has captured the attention of the 'ultimate domestic diva,' Martha Stewart.

The businesswoman and TV personality featured Leah's work on her blog when she spotted a guest at Diddy's 40th birthday party at the Plaza wearing Miller's custom-studded bowtie.

The pair delights the crowds being affable and friendly whenever the jumbotron catches them.

Bill Belichick’s girlfriend is an active participant in Patriots wives events, as well as regularly promoting The Bill Belichick Foundation.

The AFC and NFC champions are alternately considered the home team during each Super Bowl, which gives that particular team the option of picking the uniform it prefers to wear.

New England's white uniforms will also serve as a helpful reminder to Eagles fans that the Patriots edged Philadelphia in Super Bowl XXXIX, 24-21, back in 2005.

Hell, even Google trends show that the majority of people search for Bill Belichick’s wife, not girlfriend.
