The day before, Heidi donned a green bikini while splashing in the water with braid-sporting Leni.

Earlier in the week, Heidi looked pretty with a floral skirt while out and about in New York City.

FYI: Heidi is wearing Theodora & Callum‘s New York Aquarium Scarf as a wrap. Proceeds from the scarf are going to aquarium rebuilding efforts following Superstorm Sandy.
