The 'So Yesterday' hitmaker and her husband Mike Comrie welcomed their son Luca last year, and in a recent interview with People magazine, Duff mentioned they are open to having more children in the future, saying, "If I had another boy, I would be happy, but I would like to try for a girl and I'm not sure that I want to have three kids."
However, after the article was released, many took her confession as a sign the couple is already prepping for another child, a speculation Duff was quick to slam on Twitter.
"I love that I do an interview and people ask if I want more kids.. I say yes. Not now though and all of a sudden I'm trying for a girl. What? It's ridiculous.... The only baby I'm working on is my album." The 26-year-old is currently recording her fifth studio album, the first since her 2007 release, 'Dignity'.
