Both Kate Upton and P Diddy have taken to Twitter to deny reports they are Hollywood's latest power couple, following rumors of a steamy "make out" session in Miami recently. According to the New York Daily News' gossip column, the pair were spotted locking lips during a night out at the LIV club in Miami Beach, though it appears their sources were less than accurate.

An eyewitness told the newspaper, "They were kissing, they weren't hiding it," with the couple apparently partying all night in the exclusive VIP section of the club, or not, as the case may be. "Attention all Media. I don't even know Kate Upton personally!" 43-year-old Sean Combs, aka P Diddy said on Twitter. "I'm not dating her! What's being reported is not true. END of story!" Sports Illustrated model Upton, 20, also shot down the reports, tweeting, "Really??? Not at all true."

An insider has since told Us Weekly that both stars have partied at the LIV club in recent weeks, though "they weren't even there at the same time." Which sort of makes it difficult to see each other, or have a make-out session for that matter.

Upton recently split from Detroit Tigers pitcher Justin Verlander, while Diddy - previously linked to Cameron Diaz - cooled his relationship with singer Cassie earlier this year.
