Nicole Richie is expecting a boy.
The pregnant reality TV star and her partner, rocker Joel Madden – who already have 16-month-old daughter Harlow together – have been spotted buying blue toys and accessories for their new baby, which is due in August.
A source told In Touch Weekly magazine: "Joel bought water-based paint for the nursery and - surprise, surprise - it's blue! Plus, Nicole recently ordered some plush animals and infant toys, and everything just happens to be blue."
Nicole, 27, has also been referring to her unborn baby as "he". Joel announced Nicole was expecting their second child on his band Good Charlotte's blog in February. He wrote: "What's better than winning an Oscar? I am so happy to tell everyone that Harlow is going to be a big sister!
"God has truly blessed my family. Hope you're all feeling as good as I am right now."
Nicole has since revealed she is excited about the impending arrival, but has no plans to marry Joel.
She said: "I don't know about the future. I make it a custom not to plan the future. I may plan to and I may not."
