A pantless Sienna Miller was visibly shaken when approached about her seemingly less than innocent relationship with Diddy at the New York City red carpet premiere of her flick Factory Girl on Monday night.

“There is no connection other than – I, I, he, um — I met him with a load of people, and he’s a very nice guy. Thank you.” Huh?

Diddy and Sienna met at the Golden Globe Party Afterparty hosted by Prince, where they exchanged numbers. The two BFFs hooked up in Park City, Utah last week at Club Tao after chilling at the Sundance Film Festival. Sunday night marked the latest addition in the sage-Diddy was videotaped entering Sienna’s NYC hotel after partying with her at Bungalow 8.
