The 39-year-old actress took to Twitter over the weekend to share a cute pic of her 3-year-old daughter
"My little spidergirl #disneystore #kidfun," Thiessen shared on Sunday with a photo of Harper wearing a Spider-Man mask.
In the pic, Harper holds up the red-and-blue superhero mask in front of her face while wearing coordinating red-and-white plaid skirt and light blue top.
"Can you think of a better way to start the day?? #SpiderWoman," the beauty wrote along with a shot of her upside-down with he hands and feet on the ground. Refaeli's pic comes just a few days after fellow model Naomi Campbell shared a similar shot of herself in a back-bend yoga position.
