Sienna Miller & Diddy Are Totally Doing It

Sienna Miller and P. Diddy spent Sunday night (01.07.07) at a top London nightclub, sparking fresh romance rumors.

The pair were together almost all evening at the rapper's post-Concert for Diana party at top nightspot Paper.

Diddy - who has twin girls and an eight-year-old son with his long-term partner Kim Porter - had six security guards form a ring around his table to keep other revellers away.

However, after noticing how many people were engrossed by their flirtatious antics, the pair moved to a private area of the club where they relaxed behind a curtain.

A source told Britain's Daily Mirror newspaper: "Before Sienna arrived Diddy had been stranded in the middle of the dancefloor on his own table. But when he discovered Sienna was at the club, he immediately asked to be moved to the VIP area."

Sienna, 25, and Diddy, 37, initially sparked romance rumors in January after they spent a night partying together in New York, before heading back to the British actress' hotel.

However, the hip-hop star was quick to quash speculation the pair were anything more than friends, saying at the time: "I was just being a gentleman and dropping her off."
