Stefon Diggs Caught Creeping on Cardi B?

Married rapper, Cardi B, was first linked to NFL wide receiver, Stefon Diggs, in February after they were spotted together on Valentines Day [click here if you missed that]. 

Now Stef's side piece is tired of being in the shadows...

Recently a picture of Stef and Instagram model Sky Marlenee circulated online, that Stef immediately downplayed as being "old," despite Cardi's ghost writer and frequent collaborator, Pardison Fountaine, liking the pic. 

Last night Sky Marlenee set the record straight.
