Déjà vu much?!
This isn't the first time this foursome has crossed paths. Just last month, Hilary, Luca, Molly and Brooks all attended the same class.
In addition to toting their little ones to classes, Hilary and Molly have both been committed to losing their baby weight. Molly showed off her svelte bod earlier this month in a bikini Twitpic. Hilary also shared her weight loss news, tweeting out a picture of her size 26 jeans.
Way to multitask, ladies!
