Earlier this month, the show welcomed the actor back into the fold as Derek, Angie's loser ex and father of her child. ET was on the show's set in February when the cast filmed their season 2 finale, where the actress shared how Brody fit in so well on her ABC series.
"He is the baby daddy. In real life and not real life," Meester told ET's Nischelle Turner. "Sometimes I'll be like, 'Oh yeah, I forgot I'm married to you'… But it's been really nice having him here. He's very much a part of the family."
"We sure hope so. The way we ended season 2, Derek is even more a part of Angie's life (and even more of a thorn in Will's side)," she teased. "So we imagine Derek being a huge part of season 3. Honestly, he has become such an important part of our ensemble, we can't imagine doing the show without him."
Meanwhile, Meester opened up to ET in 2018 about how she and Brody have learned how to balance parenthood with their busy careers.
"I think we're a pretty modern couple," Meester said. "I think we sort of toggle back and forth... we both work, but also being actors, I think we understand each other, what we're both going through."
"I also think the nice thing about being an actor [is] you can work a lot, and when work is work, it's, like, super intense and long hours and you might not see your family for a long period. But then I'll have, like, months off at a time, so I can really be home and spend time [with Arlo]," she added. "I prefer it that way."
Meester also said that being a mom has helped her play one on TV.
"I think it kind of goes both ways, like, having a kid and being a mom. [It] prepares me to some extent, playing a mom. I bring the experiences with me. At least it's something that I've lived through," she shared.
