Cardi B is urging fans to check themselves as they hound her over her relationship with Stefon Diggs — telling them to quit being “mean” as she navigates parenthood with him and prepares for her upcoming tour.

Check out her lengthy social media video from Monday night — she lays it out plain and simple for her haters, noting … “I can’t change sh*t. I can’t go back in time. I already had a baby.”

She hilariously continues … “Y’all want me to put my baby back in my p***y? Huh? I don’t know what y’all want me to do. Y’all want me to leave my man and f*** yours?”

The “Up” hitmaker ends the video on a sweeter note, explaining she simply wants fans to come to her upcoming tour and “enjoy” the experience with her. She ends the rant by telling fans she wants love and prosperity for them all … and hopes they wish the same on her.

As you know, Cardi and the New England Patriots player welcomed a baby boy together in November after going public with their romance in May. She’s also the mom of 3 children with her estranged husband, Offset — daughters Kulture, 7, and Blossom, 1, and son Wave, 4.

Diggs is also father to daughter Nova, whom he allegedly welcomed with his ex Tyler-Marie in October 2016. He also welcomed a daughter, Charliee Harper Diggs-Lopera, in April of this year with model Aileen Lopera.
