Jason Sudeikis casually models Horrible Bosses 2 Costar Keeley Hazell after Olivia Wilde Split

Jason Sudeikis is enjoying the company of a British model, who is also his ex-costar, after his separation from longtime partner Olivia Wilde.

Sudeikis, 45, has casually seen Keeley Hazell, a source told People. The two “had known each other for many years,” adds the source, who says the actor is not looking for anything serious.

Hazell had a small role in the Sudeikis comedy in 2014 Horrible Bosses 2.

This marks the first time that Sudeikis was linked to someone after his separation from Wilde, 36, last year. The couple started dating in November 2011 and Sudeikis proposed marriage right after the 2012 vacation. They share two children – son Otis, 6, and daughter Daisy, 4.

The two have since “made the transition to a great co-parent routine,” a source previously told People.

“Children are the priority and the heart of the family relationship,” added the source.

In January, Wilde was linked to British singer and actor Harry Styles, 27, after they were seen holding hands at a friend’s wedding. A source confirmed to PEOPLE at the time that Wilde and Styles are an item.

Wilde has since been staying with Styles at his Los Angeles home and the two recently traveled to England, where Sudeikis is filming the second season of Apple TV + ‘s Ted Lasso.

Sources previously told PEOPLE that Wilde befriended Styles last fall when they started working on his film. Do not worry, dear, which she directed and starred alongside Styles.

As they spent time together on and off the set, their friendship “quickly became romantic,” said a source. “Their chemistry was very obvious.”

“Everyone saw it coming. During breaks, he was unable to stay away and visited her trailer,” added the source.

“She is very happy with Harry,” said another source later.
