The Britain's Got Talent star gave birth to second daughter Hollie Rose last month. Speaking to The Sun, Holden previously said that her heart stopped beating for 40 seconds, as she was left "moments from death".
"I'd love a bigger family - but that's it!" she told the paper. "No more - I couldn't face it again.
"Two kids is the perfect number for me. I think we'll stop at two. I think that this is what we're supposed to have. Maybe we'll get some rabbits instead."
Holden continued: "Chris is going, 'Don't even go there'. 100% no more. Although I keep joking to Chris that maybe we'll adopt some. If I'd met Chris earlier then I probably would have wanted more children. But we had a fabulous long courtship, nice meals out and brilliant holidays and now we've got two beautiful children.
"We will never forget our little boy, obviously. I said just after Hollie was born that our family is complete and I mean that. I feel so lucky that we've got to where we are. I look around the house at my husband and my two children and I think, 'This is amazing. This is perfect'."
Recalling how she and Hughes had always wanted a "coupla kids", the 41-year-old added: "And after what we've been through, there's no way I'm putting anyone through that again."
Backing his wife's decision, the producer said: "Just someone asking me if I'm going to have any more makes my stomach turn."
