Bill Belichick is all smiles with 'good friend' Donald Trump

Bill Belichick traded his customary grey hoodie and a frown for a suit and a smile during this photo opportunity with Donald Trump.

The New England Patriots head coach's girlfriend Linda Holliday posted this Instagram shot of the couple dining out with "our good friend" Trump at the Republican presidential candidate's Mar-a-Lago estate in Palm Beach, Florida, Saturday night.

The former reality TV star is also chummy with New England quarterback Tom Brady, with Trump even tweeting out his congratulations to Brady on his 2015 Deflategate ruling.
