Drake's pen might've killed Meek Mill, but it gave one fan life in London Wednesday night ... 'cause Drizzy went out of his way to get the guy's Odell Beckham Jr. jersey signed mid-concert ... by Odell himself.
Drizzy was walking through the crowd at The O2 arena last night ... when he noticed a fan with an Beckham Jr. jersey getting hyped in the audience.
Drake then called out to Odell -- who's been at multiple shows while chilling overseas -- and brought the piece to him for Beckham to sign ... as the fan freaked out.
The OVO boss then gave the freshly autographed jersey back to the fan ... and created what's probably the dopest moment in that human's existence.
And for good measure ... Drake signed it too. Canadians sure are sweet (and they can rap).
