TMZ reports that Diddy was seen dropping Sienna Miller off at her New York City hotel Monday morning, and it could mean they were doing more than partying all night. Diddy and Sienna were spotted getting cozy at a Sundance party a couple of weeks ago. Either they’re just friends or Diddy is getting busy with the British actress known more for getting cheated on by Jude Law and acting like a diva than for her forgettable work on screen.

Given that Diddy’s bodyguard is said to have tried to convince the photographer to get rid of the incriminating pictures, he does seem to be guilty about something:

Diddy, father of newborn twins, was spotted dropping off Miller at her NYC hotel this morning after a rumored night of partying together in the city. Diddy had a trapped rat look when he noticed cameras watching from across the street — and we’re told a bodyguard was sent over to the photographer to try and get him to delete the footage.

Combs and Miller were rumored to have gotten cozy at TAO nightclub during Sundance as well. Maybe Sienna’s working on a second career as a rapper.

You can watch the video here. It’s possible Diddy is just dropping Miller off, and there are a couple of people with them, which makes it seem a little less sneaky.

Diddy just had twin girls over a month ago with his longterm partner, Kim Porter. Porter is rumored to know that Diddy cheats on her regularly, and is semi-ok with it as long as he keeps a low profile. With Sienna Miller, that’s going to be difficult.

Sienna recently made boring headlines with the news that she sent an assistant to fetch her a bunch of swag at Sundance, and demanded that a gifting suite be closed 30 minutes early so that her girl could raid it in privacy.
