Bill Belichick ditched his hoodie for a blazer and took his girlfriend out on the town in L.A. on Thursday ... and TMZ Sports has the vid!!
The Pats head coach and longtime GF Linda Holliday hit up Craig's in West Hollywood ... and in rare form, the dude was grinning from ear to ear!!
BB's been busy lately ... bouncing around from the combine and pro days to check out all the potential future Patriots players prepping for the NFL Draft ... but Bill's always got time for his lady.
The couple just got back from a romantic beach vacay filled with bikini pics, golf, card games and ice cream last week.
Of course, we had to ask Bill if he's trippin' over Tom Brady's skiing videos (TB's goin' really fast) ... but if you've ever watched a Belichick interview, ya know how that went.
