Ben Affleck posted a Mother’s Day tribute to his ex-wife, Jennifer Garner on Sunday.

He shared a series of photos of Jen with their three children saying, “So happy to share these kids with you. Luckiest parents in the world. Thanks for all the good you do. Happy Mother’s Day. Love, their Dad.”

Ben and Jen were married from 2005 to 2018.  He has called their divorce “the biggest regret of [his] life,” while Garner told The Hollywood Reporter in March that they remain amicable.

“When our kids get married, we’ll dance, I know that now,” she told the magazine. “We’ll boogaloo and have a great time. I don’t worry about that anymore.”
