Did Ashton Kutcher Just Share a Photo of His 1-Year-Old Daughter?

Ashton Kutcher may have actually posted a photo on Instagram of someone he’s been trying to keep out of the public eye -- his daughter.

The Two and a Half Men alum shared a snap on Sunday of a toddler, possibly his 1-year-old, Wyatt, standing on a bridge over the Lake Hollywood Reservoir in Los Angeles and pointing to the sky with her back to the camera.

The seemingly innocent pic was accompanied by a rather serious caption from Kutcher.

“39 million people have fallen through the cracks into modern day slavery. #redsandproject” he wrote in regard to sex trafficking.

If it is in fact a photo of Wyatt, it would only be the second time the actor has shared a picture of the tot. After the birth of his daughter last October, Kutcher posted a collage of baby photos, but didn't clarify which one was his.

"Can you guess which one is ours, or does it really matter? All babies are cute," he wrote.

Mila Kunis' husband has been very protective over the couple's daughter, even going after media outlets that posted paparazzi images of her.

"Why is it so hard for publications to respect that I would like the identity of my child kept private for safety reasons?" he tweeted when the images surfaced. "Pls honor that."

Another thing Kutcher and Kunis have kept under wraps is their relationship.

The That '70s Show co-stars married in a secret ceremony in July at the Parrish Pioneer Ranch in Oak Glen, California, and of course, their daughter was right there with them.

Wyatt even got to tag along on the couple’s rustic RV honeymoon to Yosemite National Park. To see the pics from the couple’s road trip of love, watch the video below.
