Biggs and Mollen, who tied the knot in April 2008 and welcomed their first child in February 2014, also opened up about how they prioritize their marriage while balancing their careers and being parents.
"It is especially hard to have sex," Mollen answered candidly. "We have a nanny as well, living in the house, and I don't know why [but] for me, I'm just like, 'There's people here! We're not all alone!' There's just this anxiety."
"For instance, when we were on vacation [with friends], we were those people who were like, 'Should we have sex in our car?' We became those people," she added.
As for their 2-year-old son, Sid, the cute couple said they moved to New York to try to keep him from growing up and following in their footsteps.
"I really don't want him to be in Hollywood at all," Mollen shared. "I don't want him to become an actor."
"I definitely don't want him to be in a career where he's not in control of his own destiny," she continued. "I think that I learned the hard way that that's not a fun way to make a living."
However Biggs wasn't quite as dead-set against the idea, explaining, "If acting is one of those things that he wants to do, I'm not going to talk him out of that, [but] I would encourage him to experiment, [and] to be more well-rounded."
