New York, US (BBN)-Even the most powerful man in the world becomes child-like when in the presence of one.

Don't believe us? Here's a picture tweeted by the official account of the President of the United States.

President can be seen walking an unarguably cute little baby girl, Lincoln Rose Pierce Smith, the daughter of former Deputy Press Secretary Jamie Smith, in the Oval Office.

We cannot figure out whose smile is bigger in the picture but we love it none-the-less, reports NDTV.

Captioned "all smiles," this picture will melt your heart and most definitely bring a huge one on your face.

So how you would you caption this beautiful picture? Our suggestions: COTUS (Cutie of the United States) or Cutie Force One.
