The two married in a low-key private ceremony held at a friend's house on New Year's Eve. While the couple once did consider having children, they ultimately chose not to.

Speaking about their decision not to become mothers, Lily told The Guardian in 2015: "Sometimes I think it would be nice to have somebody who looks like a replica of you in some fashion. But I don't think it ever was an aspiration of mine."

"In retrospect, we say every day, 'I'm so glad we didn't have any children.' When I think of the world now, I don't want to even deal with having to raise a child."

Martin Sheen

Martin Sheen, who plays Grace's ex-husband, has perhaps the most famous family out of all the cast! He is the father of Two and a Half Men actor Charlie Sheen, who has made headlines in recent years due to his battle with substance abuse and marital problems. Martin and his wife Janet Templeton are also parents to sons Emilio and Ramón and daughter Renée.

Charlie himself has been married three times and has five children and one grandchild, making Martin and grandfather and a great-grandfather!

Sam Waterston

Sol, Frankie's former spouse in the series, is played by actor Sam Waterston, who has been married twice and has four children. With his first wife, Barbara Rutledge-Johns, he has one son named James, who followed in his father's footsteps and is also an actor.
