"We don't know!" he replied. "I've got my son Jack, and then the two girls. So we don't know, we'll wait. We wait and we're surprised on the day." Pratt shares his 12-year-old son with ex-wife Anna Faris .

Brown chimed in: "And he's not lying, I can tell. He really doesn't know."

Pratt did say he "has a feeling" about the sex, sharing, "I have an intuition but I won't say what it is in case I'm wrong and then the child sees this piece and that's confusing to them. So one day, child, you'll know I knew. I knew exactly who you were."

Earlier in the episode, Schwarzenegger Pratt, 34, appeared on the show separately, making for a cute crossover as the author called in from Los Angeles and Pratt sat with the hosts in New York City.

"Hi, honey!" Pratt exclaimed while waving at his wife on screen. "I love you. I miss you. How are you feeling?"

"I feel great. Just hope to not go into labor before you get home!" Schwarzenegger Pratt replied with a laugh. "That'd be great," Pratt quipped.

Asked how long until his wife is due, Pratt teased, "She has two minutes. Any moment now," before seriously responding, "Probably a couple of weeks."
