Jason Sudeikis filled in as a guest host for Ellen Degeneres on Wednesday's episode of the self-titled talk show. With his fiancè, Olivia Wilde, coming on as a guest on the program, he took this time ask her some hardcore parenting questions.

After the two reminisced, Sudeikis began his search for real answers. "I do want to take this opportunity in front of a bunch of people to ask you, why do you keep traumatizing our son at amusement parks?"

"No, no," Wilde said as she put her head down.

Despite Wilde's obvious resistance, the "Saturday Night Live" alum went on to describe to the audience what happened on a trip they took to Disneyland for their son's fourth birthday. After their now 5-year-old son Otis enjoyed Splash Mountain, riding the ride multiple times, Sudeikis said they got "cocky" and decided to try the Space Mountain roller coaster at the amusement park.

"It's really traumatizing for me because you're not supposed to take a 4-year-old on..." Wilde said before being interrupted by photographic evidence of the experience. "Look at my face, I've never been so scared in my life. That's real mom fear," she said.

The photo shows the actress and Otis in the front row of the ride. Hair covers the scared face of their son as Wilde holds onto him. Meanwhile, Sudeikis looks shocked in the row behind them.

One thing the mother of two doesn't have to fear, however, is her directorial debut. The actress has received rave reviews for the first film she directed, "Booksmart," which hit theatres last month.

Wilde and Sudeikis began dating in 2011 before becoming engaged in January 2013. Together that have two children, Otis and a 2-year-old daughter, Daisy.
