The 35-year-old actress reflected on how Sudeikis is a great dad to their 11-month-old daughter, Daisy Josephine, while celebrating the actor's birthday Monday.
"I have approximately one billion pictures of this guy, my partner in life-crime, who was born on this day in 1975, but this one represents his latest chapter, the one in which he became a dad to a little woman, who will grow up thinking all men can dance, sink a jump shot, and tell great jokes. Oh well," Wilde captioned a photo of Sudeikis with Daisy.
"Happpppppy Birthdayyyyyyyyy, Jason. I love you!" she added.
Wilde followed up by posting a picture of herself and Sudeikis sharing an affectionate moment at a Brooklyn Nets game.
"Last post before this guy's birthday is officially over in the East Coast and/or instagram shuts me down for copious displays of affection. Whatever, I crush hard. Find someone who makes you swoon," she told her followers. "HBD, ABC, BBD."
Wilde got engaged to Sudeikis in 2013 after more than a year of dating. She gave birth to their first child, son Otis Alexander, in 2014, and welcomed Daisy in October 2016.
"I hope to rase a child who values people for what's within them and yet I hope he experiments with his own identity and who he wants to be," the actress said of raising Otis in an interview with Yahoo! Style in July.
"I like to think he's already a little feminist. And he is. He's a really good guy," she added.
"I want to promote the idea that the definition of feminism is equality, and it's something that's not difficult to teach children because they are born with that sensibility."
