It sounds like Hilary Duff's son, Luca, is going to be an only child for a bit.

On Sunday, the singer-actress took to Twitter to debunk reports that she is trying for a baby girl. "I love that I do an interview & 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?" Duff wrote. She followed it up with, "It's ridiculous....The only baby I'm working on is my album."

Late last week, People posted an interview with Duff discussing whether she wanted her second child to be a boy or a girl. "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," Duff told the magazine.

Duff and her husband, Mike Comrie, welcomed their son, Luca, in March 2012.
