Stefon Diggs had his eyes on a cheerleader minutes after Cardi B announced the birth of their son … because he tossed her a football during his NFL game.

Cardi took to social media Thursday to announce she had given birth to Stefon’s boy … shortly before Stefon’s New England Patriots kicked off their Thursday Night Football matchup with the New York Jets.

Stefon caught a pass from quarterback Drake Maye in the first quarter and his route took him out of bounds … and when he was on the sidelines he tossed the football to a Patriots cheerleader.

Stefon already has a daughter, Nova, from a previous relationship and he’s contesting whether he fathered a child with model Aileen Lopera, AKA Lord Gisselle.

As we first told you … we obtained video of Stefon leaving a hospital with a car seat in his hands back in May … exactly one day before he hard-launched his relationship with Cardi B.

The cheerleader looked surprised Stefon even tossed the football to her … she didn’t catch the pass, but she had pom poms in her hands. 🤷🏽‍♂️

Stefon’s been known to play around with cheerleaders … taking this funny photo at the 2023 Pro Bowl.

The Pats are playing at home and Cardi B went to a game a couple weeks ago and sat with Pats owner Robert Kraft … but it doesn’t look like she’s in the house tonight.
