It's a boy for Nicole Richie and Joel Madden, say pals


's getting a baby brother.

A friend of

Nicole Richie
Joel Madden

tells In Touch Weekly magazine that the couple is planning for the arrival of a baby boy in August.

"Joel bought water-based paint for the nursery and — surprise, surprise — it’s blue,” reveals one pal, who said Richie keeps referring to the baby as "he."

Another clue: Richie recently ordered plush animals and infant toys from FAO Schwarz, and everything was blue.

This will be the couple's second child together. Daughter Harlow is 16 months old.
