Former President Obama wished his wife, Michelle, a happy Valentine's Day in a Twitter post on Tuesday.

"Happy Valentine's Day, @michelleobama! Almost 28 years with you, but it always feels new," he wrote.

The former president's message was one of his first personal messages on his Twitter account since he left the White House last month.

He and the former first lady went on vacation after President Trump's inauguration on Jan. 20.

At his farewell address, Barack Obama gave a tearful tribute to Michelle.

“Michelle, for the past 25 years, you have not only been my wife and mother of my children; you have been my best friend," he said, wiping away tears.

“You took on a role you didn’t ask for and you made it your own with grace and with grit and with style and good humor,” he added. “You made the White House a place that belongs to everybody.”

The Obamas will live in Washington, D.C. until their youngest daughter, Sasha, finishes high school.
