Sienna Miller has laughed off rumours she is having an affair with P. Diddy.

The stunning actress was rumoured to have played a part in the rap star's reported split from lover Kim Porter, the mother of his three children.

However, Sienna insists she and the hip-hop star are just good friends and she is in love with someone else.

She said: "It's true that I'm in love with someone, but not with P. Diddy, he's just a good friend."

Pals of Sienna insist she finds the romance rumours hilarious and was secretly pleased as it took the attention away from her mystery boyfriend.

One said: "Sienna just laughed when she read she was having an affair with P. Diddy. But she was happy it threw them off the scent of her real new man - who she's keeping under wraps."

Sienna and P. Diddy sparked rumours of a romance earlier this month after they spent the night at a top London nightclub.

The pair were together almost all evening at the rapper's post-Concert for Diana party at top nightspot Paper last Sunday (01.07.07)

P. Diddy 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.
