CARDI BBE MY VALENTINE, STEFON DIGGS …Offset Who???

Cardi B continues to fuel romance rumors with Stefon Diggs … ’cause the two painted Miami “Bodak Yellow” late Friday night.

TMZ has obtained videos and photos showing the rapper and the NFL wide receiver arriving to a Miami hotel in the wee hours of Saturday morning … with Cardi dressed up all sexy in a revealing dress.

Check it out … Cardi’s dress is clinging to her frame — and, when she bends forward, her entire bust is on display. Diggs dressed in all-red for the occasion, looking comfortable in a jacket and baseball cap.

Eyewitnesses tell VMHub … Cardi and Stefon got back to the hotel around 1:54 AM. It’s safe to say the two spent Valentine’s Day on the town together.

This isn’t the first time the pair has been spotted together. Just last week Cardi and Stefon were spotted together at a New York City nightclub.
