Simon Cowell Celebrates the Holidays With Ex, fiancée and Kids in Modern Family Photo

It's so sweet that they're still friends.

Simon Cowell enjoyed an extravagant Easter weekend with his blended family and friends!

The former American Idol judge, 63, and his fiancée, Lauren Silverman, 45, threw what appears to be becoming an annual Easter party this past weekend, with Cowell's ex-girlfriend Terri Seymour in attendance with her own boyfriend, Clark Mallon, and daughter, Coco.

Cowell and Seymour parted ways in 2008, but have remained close friends throughout the years, with Seymour sharing photos from the festivities on Instagram.

"Easter 2023 🐰🐣❤️💗💕," she captioned the set of springy photos. "Thank you @simoncowell & #LaurenSilverman we love you guys! 😘"

The first photo found the entire group gathered close together in the living room. At one end of the line stood Seymour, Mallon, and Coco, Seymour's head tilted in close to Silverman's, who mirrored her. Next to Silverman stood Cowell, and next to him, Silverman's 17-year-old son Adam and the couple's nine-year-old son, Eric, the latter two looking nearly identical to one another.

Seymour also showed off the snack spread, the floral decor, Coco's egg hunt spoils, and a group shot of the kids playing out on the beach, among other moments from the party.

Cowell and Silverman announced their engagement last year, telling ET at the time, “I think after everything all of us had gone through over the past two years, it has changed our lives in so many ways. Family is everything and that is what I kind of took away from it.”

Earlier this month he dished to reporters how "easy" their wedding planning is, though there's no word yet on when they'll officially tie the knot.
