Sienna Miller chose a bright pink dress to attend a charity event in England today. She was joined by her pregnant sister, Savannah, Pippa Middleton, and Poppy Delevigne for the dinner, which was thrown by All Saints in support of the Too Many Women organisation. Sienna and Savannah's mum, Jo, went along too on what was apparently her birthday! Savannah tweeted that Jo had a memorable run-in with Rolling Stone Ronnie Wood. She wrote, "Ronnie Wood just snogged mum happy birthday. Lifetime achievement award goes to . . . Mum hands down. She's grinning like a Cheshire cat!" It was a stylish evening with Pippa covering up in a long-sleeve floral look and Savannah dressing her baby bump in a black gown and red jacket.
