Sienna Miller had the company of her mom, Josephine, for a lunch date in NYC yesterday. She's preparing to take part in one of the Big Apple's most fashionable affairs by attending the Met Gala next week, and she got a head start on beautifying for the big event. Sienna and her mom visited the Caudalie Vinotherapie Spa at The Plaza hotel yesterday for a little pampering. Sienna will reportedly wear Burberry for Monday night's star-studded gala, which is in celebration of the opening of the Met's Punk: Chaos to Couture exhibit. This year's ball will be cohosted by Anna Wintour and Givenchy's Riccardo Tisci, and Sienna is not the only star headed to the red carpet. Gwyneth Paltrow, Jennifer Lawrence, Gisele Bündchen, Zooey Deschanel, Jennifer Lopez, Jessica Alba, and more will make appearances at the event as well.
In addition to the excitement of the upcoming Met Gala, Sienna has another special occasion ahead of her. She'll celebrate her first Mother's Day since welcoming her daughter, Marlowe, with fiancé Tom Sturridge last July. Mother's Day is next weekend, so be sure to take a look at all the best Mother's Day gift ideas to get ready!
