In October 2020, Foster spoke to People about spending time with her family during the COVID-19 pandemic. She shared how she, Griffin, and their daughter were sheltering in place outside New York City. “It was the first time we were all together for so long without traveling or having to leave for work every day,” Foster said.

He told how the family had made a tradition of sitting together for breakfast and dinner. “We’re all sitting at the table, and now my daughter will ask everyone, ‘How was your day?'” she shared. Foster explained how she has made this family time an important part of her day.

In November 2021, Foster wrote an essay for People about her adoption journey. She shared that she was once unsure about having children. “I was always very career-oriented, and I had a very complicated relationship with my mother growing up,” she said. But when she met Ted Griffin, things changed for her. “When I met my husband, it was the first time that I finally said, ‘Oh, I get it. I understand why people have families,'” she wrote.

Foster and Griffin were married in Santa Barbara, California in October 2014, after getting engaged in August 2013.
