Ashlee Simpson Talks About Jessica's New Baby And Her Motherly Style At The Missoni For Havaianas Launch

Ashlee Simpson hosted the exclusive launch of Missoni and Havaianas's thong collaboration at Kitson in Beverly Hills this week. She arrived looking hippie-chic in a long white maxi dress and sweet flowered headband. The new aunt to baby Maxwell Drew Johnson filled us in on her family's new addition, working on a tween line with her sister, Jessica Simpson, and how having her son, Bronx, has changed the way she dresses. Check out out some of the highlights:

• On her niece, Maxwell: "She is a doll. She's definitely the cutest thing in the whole world and is getting all the good, spoiled love. I got her a Fendi dress."
• On how motherhood changed her style: "I would say I dress for comfort most of the time. I mean, I have a daily lifestyle of being a mother as well, so I know I'm going to be picking up a 42-pound child, so sometimes heels just don't make sense. Although I wish I could be like Sex and the City and wear them all the time. But sometimes I go with a more practical, laid-back vibe. But as far as going out I like to go with my feeling. There is definitely sometimes a feeling that I love, that mod-meets-bohemian style."
• On her tween clothing line with Jessica: "The tween line is adorable and it's so much fun because we get to meet young girls trying the clothes on every day. It's just about bringing a good, fun element and the girls love these things, and it's great to meet them and find that out. I was just asking the other day if I could get all the clothes in my size. Like, can I wear a size 14 tween?"
