IF HE'S trying to worm his way back into the good books of Sienna Miller's family, Jude Law is going to have to try far harder.

Jude, 32, did his duty while girlfriend Sienna was working on her new flick, Factory Girl, in New York. He pitched up at a charity event in Notting Hill on Thursday hosted by Sienna's step-sister Natasha Corrett.

But a fellow partygoer revealed: "After chatting to Sienna's sister and stepmum Kelly Hoppen for 10 minutes, he spent the rest of his time with a pal in the corner. He didn't seem happy to be there and left after only an hour."

And Natasha, daughter of Sienna's stepmum, admitted: "He's here as a favour - he IS my sister's boyfriend."

The Alfie star proposed to Sienna last Christmas but cheated on her with his kids' nanny. The couple are all loved-up again but Jude's still reluctant to talk wedding bells. When asked about matrimony Jude muttered: "Er, I can't say... maybe I can answer that another time."
