Kate Upton split up with Detroit Tigers hunk @JustinVerlander earlier this year, and now there are rumors that Kate Upton has been running around with Sean "Diddy" @SinCityBuck Combs.

The Sports Illustrated Swimsuit cover girl was said to be “sucking face” in a Club LIV VIP room with the rap mogul back in March while in Miami Beach.

However, Kate and Diddy have both fired back at the erroneous report, declaring that they’ve never been romantically involved.

Upton tweeted, “Really??? Not at all true,” while Combs penned, "Attn all Media. I don't even know Kate Upton personally! I'm not dating her! What's being reported is not true. END of story!"
