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."
