Michelle Obama was in the middle of a question-and-answer session at the Pennsylvania Conference for Women when a video featuring Barack Obama played, surprising the former first lady.

"Hey honey,” the president began. “Listen, I know you are with all these important Pennsylvania women ... but I had to crash this party because today we have been married for 25 years.”

In the two-minute video, Barack Obama gushed about his wife, calling her a “saintly, wonderful, patient person.”

“Not only have you been an extraordinary partner, not only have you been a great friend, somebody who could always make me laugh, somebody who would always make sure that I was following what I thought was right, but you have also been an example to our daughters and to the entire country,” he said.

The interruption was met with applause, laughter and “awwwws”  from the audience as Michelle Obama blushed onstage.

The Obamas celebrated their 25th anniversary on Tuesday. Michelle Obama posted an anniversary message on her Instagram page that has been liked 2.2 million times. More than 40,000 people also posted comments on it.
