As President of the United States, Barack Obama is usually the centre of attention wherever he goes.
But when he paid an impromptu
visit to a Christian school in Florida, one little boy managed to steal the scene in style.
The amorous youngster was pictured in the background of Obama's photo-op planting a kiss on the cheek of a classmate, and the image is fast becoming one of the most popular of the presidential campaign so far.
The charming moment took place at Daughter of Zion Junior School in Delray Beach, Florida on Tuesday.
这样可爱的一幕拍摄于周二，地点是在弗洛里达州东南部城市德尔雷比奇的Daughter of Zion 小学。
Students from the private Christian school had gathered outside to wave to Obama's motorcade
as it passed - so the President decided to stop and pose for a photograph with his young fans.
But as the picture was being set up, a boy in the back row turned to girl sitting next to him and gave her a kiss on her cheek.
It was the Obama campaign which first drew attention to the hilarious
photo-bomb, when it tweeted the picture on Tuesday evening.
The picture has since spread around the world, as thousands of people embrace the chance to witness the more human side of the campaign trail.
In fact, the one person who does not seem to have been delighted by the kiss is its recipient. The girl appears shocked by the unwanted attention, and can be seen wiping
her face in a shot taken seconds later.
A spokesman for the school said they were unfazed by their new-found fame, and were pleased to have hosted Obama.
'We were just happy to have been with the President,' she told MailOnline. 'We were just happy to have the honour.'
