Eight weeks after welcoming her third child, son Joshua Bishop Jr., Katherine Heigl is ready to have more kids!
The 38-year-old actress got candid about her family plans while chatting with ET's Cameron Mathison backstage at The Late Late Show With James Corden in Los Angeles, California, on Tuesday.
"I think once you have two, it doesn't matter anymore!" laughed the Doubt star, while pondering whether three kids are exponentially harder to handle than two. "You've already got two...right?"
Asked if she was hinting that she wants to further expand her brood, Heigl admitted that she's already raised the subject with her musician husband, Josh Kelley.
"I've already tried to have this conversation, but it's so funny -- at eight weeks, he's like, 'I'm not talking about this right now!'" she said.
The couple have two adopted daughters -- 8-year-old Nahleigh and 4-year-old Adalaide -- and were taken by surprise when Heigl found out she was pregnant with baby Josh.
This kid...just YUM! #littleman #joshuabishopjr #babybliss

"It wasn't planned," she shared. "I did want to expand our family -- we just weren't sure how we were going to do that and I'm all about preparation and planning and timing. Sometimes you just can't do it that way or you get 'surprised' with something and you have to make it work."
"It ended up working so much more beautifully than I ever could have imagined and the fact that we wrapped up filming in December and now I have all this time with him to just be mom ��� it's such a blessing," she added. "I'm so grateful."Heigl went on to gush about how proud she is of her children, happily letting baby Josh make his national television debut on the hit CBS late night show.
"I just keep tossing that kid out in front of the cameras ... all of my children!" she joked. "I'm just so proud of them and I think they're so amazing and find them far more interesting than me in so many ways. So it's easier for me to push them out there in front of the camera... sorry kids!"
The actress was looking stunning at the talk show appearance, and credited not "beating myself up like I normally do," for her amazing post-pregnancy figure.

"I didn't emotionally, mentally or physically go, 'I'm going to beat my body into submission,'" she shared. "I just went, 'You know what? Just relax about this.' Sometimes the more focus I put on dieting and getting in shape, the harder it is for me to do it. I don't know if I become more food-obsessed or what happens, but this time around I just said, 'I'm going to give myself whatever time I need. I don't want to kill myself over this right now.'"
Heigl's new legal drama, Doubt, premieres Wednesday night on CBS, and she opened up about being comfortable with her physique while filming some of the show's steamier scenes.
"Thankfully, my husband was incredibly supportive of my pregnant body," she gushed, "but as a woman, it's a little bit hard when [you struggle with] your mental image of what you're supposed to be in a moment like that on television with your co-star. You're supposed to, you know, have the six-pack abs and the cute little toosh."
The actress said she's had a great time playing her "fun, complicated" Doubt character, Sadie Ellis ��� "She's ambitious and she's smart and she's talented, but she has these flaws and vulnerabilities and this baggage" -- but admits that's she's struggled a bit with the legal jargon, moreso than the medical terminology she used to memorize for Grey's Anatomy.
"I don't know why, for some reason I'm stumbling up on the legalese more than I did with the medical jargon," Heigl said with a laugh.
Doubt airs Wednesdays at 10 p.m. ET/PT on CBS.
