Rapper Sean Combs has dismissed speculation he's romancing actress Sienna Miller, despite being spotted flirting with the blonde beauty after Sunday's (01Jul07) Concert for Diana. The hip-hop star is currently dating model Kim Porter and is adamant his cosy chat with Miller at the lavish London after-party following his Wembley performance was innocent. He says, "Yeah, we all hang out together but there's no more to it than that." Combs was recently spotted sneaking into the 25-year-old's hotel at 9am after a night of clubbing in New York, but he insists, "I was being a gentleman and dropping her off."
