Anthony Davis' Parents Surprise Him W/ Birthday Cake After Historic Game

Anthony Davis' parents had several reasons to celebrate after the Lakers' massive win on Sunday ... their son's historic performance and 31st birthday -- mom and dad even surprised him with a massive cake right in the locker room!

The Lakers center put on a show at the Crypto.com Arena against the Minnesota Timberwolves (who were without Rudy Gobert and Karl-Anthony Towns) ... finishing the game with 27 points, 25 rebounds, seven steals, five assists, and three blocks.

AD's folks, Anthony Sr. and Erainer, were in attendance to watch their son ... and he was incredible. The 'rents then got to surprise him with a big cake for another trip around the sun.

The Lakers helped out, too ... as mom and dad walked in, players, including LeBron James, began singing "Happy Birthday!"

AD was all smiles ... and rightfully so. His stat line from Sunday's game was a first for an NBA hooper.

"We just want to come out as a team effort knowing that where we are in the standings and how important this game was," Davis said during post-game interviews, "You know, trying to close the gap in the standings."

The Lakers are currently the 9th seed in the West, moving just one game behind the Dallas Mavericks.
