Say what you will about the Obama presidency, there was one part of the former President's life that won hearts nation wide. Good, authentic, old fashioned romance.

Trump's inauguration was full of monumental moments; from his first speech as the 45th President of the United States to enough glamour to rival the Oscars, it was one for the history books.

But, aside from all the performances and fanfare, there was one sweet moment that some might've missed.

While waiting for the Trumps to arrive at the White House, Barack and Michelle once again proved why America is so in love with their relationship.

As they stood outside awaiting the Trump convoy, Barack leant over to give Michelle a kiss on the cheek and she followed up his peck by brushing the shoulders of his suit.

The adorable interaction wasn't out of the ordinary for the pair and thankfully, was also captured on video.

Barack was later snapped giving his wife's hand a kiss as they stood on the capital steps.

It's these small gestures that kept the Obamas so high on America's sweetheart list, whether it was holding doors open or walking in the rain so Michelle could stay dry under umbrellas, Barack was all class.

Plenty of celebrities have taken to social media to pay tribute to the 44th President of the United States.

“I’m asking you to believe. Not in my ability to bring about change — but in yours.” Terribly sad to see you go but honored I was able to watch firsthand. I hope our history books will do you justice.
