Former President Barack Obama surprised Michelle Obama with a video tribute on Tuesday to celebrate the couple's 25th wedding anniversary.

The former first lady was wrapping up a question-and-answer session at the Pennsylvania Conference for Women when moderator Shonda Rhimes revealed an unexpected surprise.

"It's been a very special day for all of us, but I also know it's a very special day for you. And so I have a little bit of a surprise. Can you roll the video?"

A video of the former president then began playing as Michelle broke into a wide smile.

"I had to crash this party because today we have been married for 25 years," President Obama said in the video, prompting loud cheers from the audience.
