Diddy: I'm not dating Kate Upton

Both Sean "Diddy" Combs and model Kate Upton set the record straight Wednesday after a report surfaced that said they were dating.

The rapper/mogul shot down the speculation via Twitter, writing:

According to the New York Daily News, Diddy, 43, and the 20-year-old Sports Illustrated cover girl had been spotted kissing at a Miami club last month and were seen together again last week having dinner in New York.

A rep for Upton also called the report false, telling the Daily News: "They met once a year ago and there's no further relationship at this point."
