P Diddy and Kate Upton denied the rumors that there was something going on between the two via Twitter

Rumors swirled that the rapper, 43, and supermodel, 20 were hooking up, but Diddy denied that there was anything to the rumors. He said he doesn't even really know her.

"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!" Diddy tweeted Wednesday.

The possibility of this new couple started when Daily News Confidential reported about a make-out session between Diddy and Upton.

"After the 20-year-old Sports Illustrated Swimsuit Issue cover girl said she was single on Valentine's Day and had broken up with star Detroit Tigers pitcher Justin Verlander, she was spotted a little over a month later, on March 24, sucking face with Diddy, 43, at club LIV in Miami Beach," Confidential previously reported.

The newspaper dubbed the couple as "Diddyup" and that they're relationship was "hot and heavy."

Upton disputed these rumors as well.

"Really??? Not at all true.."@TheCut: .@KateUpton and @IamDiddy seen sucking face and dining out!" Upton tweeted Wednesday.

Upton has yet to publically acknowledge Spike Albrech's tweet after his breakout performance during the NCAA championship game Monday. He averaged less than two points during the 2012-2013 regular-season with the runner-up Michigan Wolverines in the national championship, and overnight became a household name when he tallied off 17 points in the first half of the finals against the Louisville Cardinals.

@KateUpton hey saw you at the game last night, thanks for coming out! Hope to see you again!" Albrecht tweeted at Upton Tuesday.
