Linda Holliday, Bill Belichick's girlfriend, posts PDA on Instagram

Bill Belichick doesn't seem like a warm and fuzzy kind of guy. In fact, the New England Patriots head coach has a public persona that is actually quite the opposite. But if you follow The Hoodie's longtime girlfriend, Linda Holliday, on Instagram, you might have a different perspective. The former high-end retail business operator often posts unlikely images of the football personality known for his gruff demeanor. Remember this shot from back in March?

Holliday's latest post showed her on Torrey Pines Beach in the San Diego, Calif. area (the Pats will face the Chargers on Sunday Night Football in Week 14) with a heart featuring her and Belichick's initials. The caption reads, "He captured my heart a long time ago ... And still makes me glow! BB"

Belichick may not seem like the most lovable guy — but don't tell that to Holliday. Her very public display of affection says otherwise.
