The Scandal actress also marked the special occasion by sharing a carousel of photos from their relationship over the years.

"13 years ago I married the love of my life," de Rossi wrote. "And it just keeps getting better ♥️🥂."

In February, the duo opened up to PEOPLE about their romance and shared how they prioritize their relationship amid their busy schedules.

"We've grown together as a couple, and we really consider each other and put our relationship first," de Rossi said. "By doing that, you become a lot more solid. I can't imagine spending time with anyone but her."

DeGeneres added, "We think the same things, say the same things at the same time, finish each other's sandwiches — no, sentences. We're in a rhythm that's easy."

When asked what they love the most about each other, the Finding Dory star said, "To start superficially, I love the way she looks. I love her brain; she's smart. That's really important."

"She's strong. She's confident. She's really funny. And she's a good dresser and a good dancer. She's learning to cook," she added of her wife.

Snuggling up to DeGeneres, de Rossi laughed and said, "Wow, how do I top that? She is the kindest, most generous, most loving, loyal, trustworthy person I have ever known. She's a very special human being. Some of it sometimes rubs off on me."
