Sienna Miller and Jude Law are working hard to mend their relationship, and are still very much in love according to the Alfie actress' step-mother.

The troubled screen stars' relationship hit the rocks when news of Law's infidelity hit newsstands in July (05), but Kelly Hoppen insists they are keen to put their past behind them.

She says, "I'm sure they'll get through it. Jude loves her and he's really showing that. The whole family can see they are trying to make it work.

"She has to deal with her tears in public which makes it hard. But Sienna is a beautiful girl who will get through it."
