Olivia Wilde and Jason Sudeikis are no longer an item … the couple’s reportedly called it quits after a lengthy engagement, during which they started a family.

The actors secretly ended things at the beginning of this year, though they’ve been able to successfully co-parent their 2 young children … according to People. The report also describes the breakup as amicable.

Sudeikis and Wilde first started dating in 2011, and Jason proposed the next year. Olivia said yes … but, barring reconciliation, there won’t be a walk down the aisle.

They were last seen together in September, and the pics of them on a Malibu beach appear to show they’ve remained friends after the split … or maybe even tried to work things out. It doesn’t appear their kids — 6-year-old Otis and 4-year-old Daisy — were with them on the beach trip.

We reached out to reps for both Jason and Olivia … so far, no word back.
