The O.C. alum Rachel Bilson gave her daughter Briar Rose a big kiss and a hug goodbye during a custody hand-off with her ex-fiancé, Golden Globe nominee Hayden Christensen, outside his Los Angeles home on Saturday.

Custody arrangements can be even more complicated for former couples in the age of COVID-19 quarantine, and LA County’s stay-at-home order was extended through May 15.

The 38-year-old LA native, the Canadian 39-year-old, and their five-year-old princess were not wearing cloth face masks as recommended by the Center for Disease Control on April 3.

‘I have known Rachel since she was in college because she was a friend of my daughter Zoe. So she was in our backyard! And now all of a sudden, she is in relationship with my co-star, my friend, and my boss.’

The It Chapter Two actor has three daughters – Hannah, 10; Harper, 7; and Hayley, 5 – from his 11-year marriage to TV director Maggie Carey, which ended in 2018.
