In November 2022, a source confirmed to PEOPLE that Evans and Baptista were officially dating. At the time, the source said the two had been dating “for over a year and it's serious.”

"They are in love and Chris has never been happier,” the insider added. “His family and friends all adore her."

"That's absolutely something I want: wife, kids, building a family," Evans told PEOPLE just before news of his relationship went public. "When you read about most of the best artists, whether it's actors, painters, writers, most of them [admit] it wasn't the work they made [that they are most proud of], it was about the relationships; the families they created, the love they found, the love they shared."

"I love the idea of tradition and ceremony. I had a lot of that in my life, so the idea of creating that — I can't think of anything better,” he said without any hints of the special woman in his life.

Evans and the Portuguese actress made their relationship Instagram official in January. 

"A look back at 2022 ❤️❤️❤️," he wrote on a video shared to his Instagram Story at the time. In the clip, the two laughed as they played a sweet prank on one another while doing laundry. 

For Valentine’s Day, Baptista made another cameo on his Instagram Story when Evans revealed to his followers that he taught her all about Super Mario Bros. 3. “She hates this video but I LOVE it,” he wrote on a video of her playing the classic Nintendo game.

On Monday, a source told PEOPLE that things "got serious very quickly" after they met in Europe. "He kept saying he knew she was the one."

"He has been ready to settle down for a while," said the source. "He can’t wait to have a family. He was just waiting for the right girl."

"She is beautiful, smart, and just a good person," the source added. "She is involved in charity work and truly cares about doing good. It's the best news that they are married."
