Olivia Wilde and Jason Sudeikis have split.
The pair — who have son Otis Alexander, six, and daughter Daisy Josephine, four, together -— were engaged for seven years but reportedly ended their relationship earlier this year.
A source told PEOPLE: "The split happened at the beginning of the year. It's been amicable and they've transitioned into a great co-parenting routine. The children are the priority and the heart of the family's relationship."
Jason, 45, and Olivia, 36, started dating in 2011 and he proposed the following year.
Speaking previously about falling for Olivia, Jason said: "I met her at a finale party for Saturday Night Live. We hit it off that night.
"I actually came off looking a little cooler than I really am because I had heard through the grapevine, through mutual friends who weren't exactly her best girlfriends, who would report back, 'Oh you know, I think she's dating someone'. So I didn't make any moves. I was just very, very busy with other things. And next thing you know, I stopped being busy, she stopped dating someone, and then it was off to the races.
"We sort of reintroduced ourselves. The universe had more in store for us in the fall."
Olivia explained that Jason didn't ask for their number when they first met, adding: "Over the next six months we kept running into each other. One night, my best guy friend walked up to him and said, 'This is Olivia's number. Use it.' That was the beginning."
