Olivia Wilde‘s fiancéJason Sudeikiswas born with an odd condition — but their 4½-year-old son,Otis Alexander, knows how to fix the problem!

TheLife Itselfactress, 34, opened up toJimmy Kimmelon Monday night about the fact that theHorrible Bossesstar, 43, can’t smell or taste anything.

“Apparently it took quite a while for him to realize it,” Wilde told theJimmy Kimmel Livehost. “I had weirdly heard it from our mutual friends, and it was an awkward thing I brought up on our first date. I was like, ‘I heard you don’t smell so great.’ ”

It’s also become a bigger problem as their relationship has progressed. “When our kids were born, he had a realForrest Gumpmoment where he was like, ‘Is he normal? Can he smell?’ ” Wilde recalled, adding, “and Otis can smell, which is lucky for him.”

In fact, Otis feels so blessed compared to his dad that he desperately wants to help him, Wilde shared.

“He’s convinced he’s gonna diagnose the problem and fix it,” the mom of two explained. “So he’s like, ‘Dad, there is a Lego up your nose. You just have to breathe out really hard.’ He tries to coach him. He holds his face. He’s like ‘I’m gonna get it. Don’t worry.’ ”

Another minor frustration for Wilde? “He’s still weirdly squeamish about picking up dog s— which is confusing to me,” Wilde bemoaned of Sudeikis. Then she called her partner “a superhero designed to pick up s—. You are impervious to the problems associated with s—. He’s afraid of his power. He hasn’t come to embrace it yet.”

But Sudeikis’ nose certainly has its pros.

“The good thing is he thinks I am an incredible chef because he can’t taste anything,” Wilde said. “It’s a pretty crazy thing. But I guess if you’re gonna lose a sense … New York in the summer time, you don’t want your sense of smell.”

When Kimmel asked the one thing theHousealum wishes Sudeikis could sniff, she swiftly responded, “Sautéing onions. Garlic and onions. The beginning of a pasta.”

In July, Wilde posted on Twitter after the trailer was released praising the script and offering fans a little tease of the emotional roller coaster the story will bring.

“Very few scripts make you laugh hard, ugly-sob, and then scream ‘wait, WHAT?!?!! Can they DO that?!’ I loved making this movie,” she wrote.

The film hit theaters on Sept. 21.
