The Baldwin family might be growing again! While appearing on The Ellen DeGeneres Show on Monday, February 4, Alec Baldwin revealed that his wife, Hilaria Baldwin, wants to have a fifth baby to give their eldest child, daughter Carmen, 5, a little sister.

“Does she want more?” host Ellen DeGeneres asked the 60-year-old actor, to which he replied, “I think she wants one more. She wants to have a girl. She wants Carmen to have a little sister.” Later on in the episode, Hilaria, 35, joined her famous hubby on the show to play a game. But before that could happen, Ellen had to ask the yoga instructor if she really wanted to get pregnant with baby No. 5.

“He says you really want another baby — you want another girl?” Ellen asked Hilaria and she confidently replied, “Yes!” When the host then asked the mom-of-four — she also has sons Rafael, 3, Leo, 2, and Romeo, 8 months, with Alec — what would happen if their next child ended up being another boy, Hilaria said, “You have to keep on trying, Ellen! I’m serious.”

The proud mama continued, “When I told Carmen — our 5-year-old, everything revolves around her — that I was pregnant with another boy, she said, ‘Mommy, how about you have another girl then you can have another boy.’ And I said, ‘It doesn’t work that way.’ So she asks me all the time when she’s going to have her sister.”

This actually isn’t the first time Alec — who is additionally a dad to 23-year-old daughter Ireland Baldwin with his first wife, Kim Basinger — and Hilaria have spoken out about adding another baby to their family. “I think about it a lot,” Hilaria said in an Instagram story posted last fall. “When I’ll have a day that’s really hard with the kids and I’m like, ‘No more kids!’ And then I have a day where they’re like really cute like this and I’m like, ‘I could have another one.’ We’ll see.”
