Jason Sudeikis has a bone to pick with girlfriend Olivia Wilde! When the 43-year-old actor guest-hosted The Ellen DeGeneres Show on Wednesday, June 12, he revealed how Olivia, 35, traumatized their 4-year-old son, Otis, during a recent trip to Disneyland.

“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?” Jason jokingly asked the Booksmart director on the show. “This is important, this is something I wanted to bring up.”

Jason explained that a relaxing trip to Disneyland quickly turned ugly when he and Olivia decided to take Otis on the Space Mountain ride. “It’s really traumatizing for me because you’re not supposed to take a 4-year-old on [the ride],” Olivia admitted after Jason showed the audience a photo of them on Space Mountain.

Olivia can be seen holding onto Otis, whose hair is covering his face, in the funny snap. They appear to be sitting in the front of the ride as Jason occupies the cart behind them looking very scared.

“Look at my face! I’ve never been so scared in my life! That’s real mom fear!” Olivia told the audience before Jason chimed in himself. “And that’s real little boy fear. He looks like he’s in The Ring!”

The proud parents of two might want to think twice before they decide when Otis’ 2-year-old sister, Daisy, goes on a adult ride — just saying.

“First of all, why did we go in the front? That I’ll never understand,” Olivia said, defending the decision. “Second of all, why did they let [Otis] on? There’s a height chart, but there’s no weight chart. So he’s really tall, but he’s really skinny, he’s like a little string bean. He could have flown right out of there. I have never been so scared in my life.”

We doubt Jason and Olivia will be making this mistake again anytime soon.
