Last month, the Britain's Got Talent judge almost died after suffering blood loss during an emergency C-section to deliver Hollie - leaving her to state that she "couldn't face" having any more kids.
Holden, who previously suffered a miscarriage in 2010, told The Sun: "I'd love a bigger family - but that's it! 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.
"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'. And after what we've been through, there's no way I'm putting anyone through that again."
Hughes went on to back his wife's decision, adding to the tabloid: "Just someone asking me if I'm going to have any more makes my stomach turn."
