Bill Belichick continues to be the base to Jordon Hudson's flyer ... as the 73-year-old was spotted cheering on his 24-year-old girlfriend at a competition in Atlanta over the weekend.
TMZ Sports obtained photos of the couple looking happier than ever on Sunday. Belichick -- rocking a buttoned shirt and a Navy submarine hat -- was seen alongside Jordon, who was all dolled up in her cheerleading uniform.

Hudson once again suited up for Code Black .
