In an interview with People, Jill confirmed the corsage was a surprise from President Joe Biden and is actually part of a longstanding tradition the two started on Valentine's Day years ago.

"I love gardenias, and so Joe would buy me a wrist corsage of gardenias," Jill said. "It's just a tradition. He surprised me with it."

"I was surprised that people actually saw it on my wrist," she continued. "I guess with a zoom lens you see everything."

"I think it's important, and Jill does the same thing, to let each other know no matter how much time has gone by," Joe Biden added, before placing his hand over his heart. "She goes down the steps and it still goes a little boom, boom, boom, boom. For real."

During their interview with People, the couple also discussed how they have supported each other's careers throughout their 43-year marriage.

"I think we each could've done our jobs without the other, but not as well as we do them," the president said, adding that he was glad Jill has continued working as a teacher.

Biden also credited his wife with his political success and said he doesn't think he "would've stayed involved in public life" without Jill.
