Webmistress’s note: We don’t post gossip or things about Sienna’s personal life here anymore, but seeing as this comes from the mouth of a very reliable source, I think this article is ok.

Sienna Miller is rumoured to be marrying Jude Law this summer, but her sister, Savannah, a fashion designer, does not expect to be asked to create the bridal gown.

“There will be a lot of competition from the likes of Galliano and other designers, so I doubt I’ll be making her dress,” says Savannah, 31.

Sienna, 28, broke off her engagement to Law, 37, in 2006 after the actor admitted sleeping with Daisy Wright, his children’s nanny.

Last year, Savannah was keen to rubbish (correct) reports that the pair had been reunited after Law fathered a daughter, Sophia, from a brief relationship with Samantha Burke, a model and aspiring actress.

“I think that would be a completely ridiculous assumption considering the way that man has conducted himself recently,” she told Mandrake. “That’s all I’m saying.”

Happily, they are all now friends. “We spent two weeks in Puglia in southern Italy and swam, cooked and chilled out together,” Savannah says of her recent holiday with Law and his children. “I hardly ever go away but that holiday made me realise that family and your loved ones are what’s important.”
