Did Ashton Kutcher share his daughter's pic?

He might have been a protective father since his daughter's birth, but Ashton Kutcher might have shared a picture of Wyatt Isabelle.

The 37-year-old took to his Instagram and shared a photo of a baby girl holding onto a railing and pointing. She's standing on concrete, with the cracks filled with red dust.

Kutcher captioned the pic, "39 million people have fallen through the cracks into modern day slavery. #redsandproject."

While Kutcher hasn't confirmed if the tot in the photo is his daughter, speculation immediately went into overdrive about who the mystery bub could be.
