Lori Loughlin posted a cute birthday wish for her TV husband John Stamos on Wednesday. Sharing an adorable photo of her 52-year-old Full House costar, which looks to be from the day the cast celebrated Lori's recent birthday [1], she wrote, "Happy Birthday to one of the best.

The group is busy shooting the Netflix reboot, and several of the returning Full House cast members [4] have already shared awesome photos from the set [5].
