Lots of claims about celebrities sucking their thumbs are just a paparazzi shot of one touching her lips with her thumb, or they're just posing for a particular image. Or perhaps they just cut themselves. What we're looking for is celebrities who actually suck their thumbs. Looked and found
This is clearly a genuine thumb sucker. No posing, no accidental touching, but true and honest comforting with her thumb. That's what makes this photo so great. It's real. Here's another photo.
This is from a radio interview where she briefly talked about her thumb sucking. Here is the video clip of that part.
is a great photo of her sucking her thumb. According to the same source, she also wrote about it. More photos are linked there too.
Actually this shot
is more of a poser for a photo shoot with awesome photographer Terry Richardson (who also sucks his thumb on the photos). But she landed here because of the sheer beauty of the photo.
It's hard to tell for sure how genuine her thumb sucking is. It was a photo shoot for Vogue so that raises doubt. Also the fact that she's looking into the camera doesn't help either. Real thumb sucking would probably not have her attention on what's going on around her. But those aren't evidence and since the actual posture is real and the photo is lovely, she gets featured here.
Absolutely gorgeous photo and it looks very genuine. Might still be a pose but that doesn't matter given the beauty of the shot.
Here is a piece of an interview with her:
MR: I know you've been sucking your thumb for many, many years. What's that about?
NH: When I was little I sucked my thumb and then later when my teeth came. When I became an adult I was still sucking my thumb, occasionally. Here and then, there and that. So my teeth, they go a little up and down.
MR: When did you stop sucking your thumb?
NH: I never did.
