Well, that was fast. Diddy took to Twitter to confirm he is not dating Kate Upton.

Earlier today, a rumor was hitting the Internet about an alleged relationship with 20-year-old Model Upton and Sean “Diddy” Combs. An eye witness says, “They were kissing, they weren’t hiding it.”

The source says Diddy invited Upton during his party at Club LIV in Miami. They were seen partying throughout the night.

Another source says the duo met in New York and shared a romantic dinner together.

We guess Diddy doesn't like gossip news of any kind.
