Former President Barack Obama and first lady Michelle Obama exchanged sweet messages on Valentine's Day.

Sharing a picture of the two dancing at a White House party in 2010, Barack paid tribute to his "extraordinarily smart, beautiful, [and] funny]" wife.

Then Michelle tweeted a picture of the couple with their two daughters, writing that she was "so lucky to call these three my valentines."

The Obamas paid tribute to each other on Valentine's Day by sharing throwback pictures and sweet messages on Twitter.

Former President Barack Obama kicked things off Thursday afternoon, sharing a photo of him dancing with his wife at a White House party in 2010.

"Happy Valentine’s Day to the extraordinarily smart, beautiful, funny, one and only @MichelleObama. It's true; she does get down to Motown," he wrote.

Half-an-hour later, Michelle crafted a Valentine's Day message of her own, alongside a picture of her family from the night in 2004 that her husband won a seat in the US Senate.

"So lucky to call these three my valentines for all these years," Michelle wrote.
