She said: "When we were home and we would be watching something, the show was, and there was Jennifer and Julian my son would be like 'mommy' and my son couldn't see the difference.
"When he did see Jennifer, he would crawl into her lap." She then joked "You prefer her, that's fine, a lot of people do. She's lovely."

Until the end of the final season of Friends, when Courteney Cox became pregnant with daughter Coco, Lisa was the only member of the cast who was married and with a child.
Rob asked Lisa what it was like for the star: "You were married, you had a small baby, you were in a different phases of your life. That must have added something cool and different – you were totally ahead of everybody in leading your life."
Lisa replied: "When I was there, I was there. It's not like, my son was so little, I think he was five or six when we finished.

"A set really isn't a place for a toddler to be running around. It wasn't a fun place for him. He wasn't there much as it turns out. It was fine for a quick visit but not to spend all day with mommy.
"I did not like him experiencing me not as mommy. Because Phoebe was not his mother, Phoebe does not have children."
Lisa shares Julian with husband Michael Stern, and the family have been isolating at their home in Beverly Hills during the pandemic.
