Lily Aldridge and Erin Heatherton spent a day shopping in NYC on Sunday. Along for the ride with the two models was Lily's 4-month-old daughter and Erin's goddaughter, Dixie Pearl Followill, who likely scored some goods during their stop at the Marc Jacobs kids store. Lily also set out on a solo trip with her little one on Monday, covering Dixie's stroller from the sun with a blanket. Both Lily and Erin are gearing up to walk in this year's Victoria's Secret Fashion Show, which airs on Dec. 4. It will mark Lily's first modeling gig since giving birth back in June, and it seems that she's really excited. Lily shared a photo of herself during a VS fitting last week, tweeting "I'm back!", and recently spoke about her amped-up workout routine ahead of the big show.
