Cardi B and Stefon Diggs Unfollow Each Other on Instagram, Spark Split Rumors

Cardi B and Stefon Diggs could be dealing with some trouble in paradise ... at least that’s what fans think after the two unfollowed each other on Instagram.

Of course, this comes on the heels of Diggs and the New England Patriots’ Super Bowl loss to the Seattle Seahawks. Eagle-eyed fans were quick to notice the unfollowing -- and we checked for ourselves … it’s legit. That said, it’s unclear whether the unfollowing happened before or after the tough loss.

The potential split is sending shockwaves online ... not only does it follow Stefon’s disappointing defeat, but it also comes just a few months after the couple welcomed a baby boy in November 2025.

If something did go down, it appears to be recent ... Cardi had been a total ride-or-die throughout the Pats’ Super Bowl run -- regularly at games and proudly backing her man on social media.

However, she didn't seem too enthusiastic about Stefon on Saturday night, when an ESPN reporter asked if she had an inspiring message for him, and she bluntly replied, "Good luck."

FWIW ... Cardi made a subtle appearance during Bad Bunny’s halftime show performance Sunday night.
