Rachel Zoe held her son Skyler's hand as they walked in LA yesterday. The one-year-old is on the go after showing off his balancing skills during a shopping trip with Rachel in April. It's been an exciting month so far for the busy mom, who attended the Met Gala in NYC with model Karolina Kurkova last week. Rachel also celebrated Mother's Day on Sunday and tweeted that the holiday is "officially my favorite day of the year forever!" The fun continued last night at a charity event held at the Elyse Walker boutique, where Rachel's eponymous Spring collection was on display.
