You are an incredible, amazing, beautiful boy inside and out." Awwww!

Paltrow spent time at the beach in a unique bikini with the family. And on Easter, Paltrow gave Moses and Apple two adorable rabbits (what a fun mom!): Gwyneth Paltrow Hits the Beach in Scalloped Bikini sith Chris Martin Moses's big day wasn't the only birthday Paltrow celebrated this week.
