Bilson, who split from Hayden after 10-years together in September 2017, shared a rare glimpse of Briar Rose Christensen to celebrate Mother’s Day.
"Happy Mother’s Day to all the moms out there who’s alarm clocks are drop kicks to the face. I wouldn’t trade that wake up call for anything in the entire world, becoming a mother has been the greatest gift and now I know the actual meaning of true love," the Hart Of Dixie actress shared alongside the sweet photo.
"Celebrating all mums today in every form. And the biggest thanks to my mum who has the biggest warmest heart, you have taught me so well. you’re my best friend and I love you."
Rachel and Hayden's decision to part ways was partly due to their conflicting work schedules, reports from Us Weekly, "She’s full-time back in L.A. He’s in Toronto,” says the insider. "They’ve been on the outs for a couple of months.”
Bilson, 36, gave birth to their daughter, Briar Rose, in October 2014. They met on the 2008 film Jumper and Christensen, 36, proposed just a few months later.
