File photo in April 17, 2008 shows pop star Ashlee Simpson arrives at the Conde Nast Traveler 8th Annual Hot List party at Mansion in New York .
Ashlee Simpson and her rocker hubby Pete Wentz are reportedly expecting a boy.
The couple announced Simpson's pregnancy last month, just weeks after their wedding ceremony in California.
They have refused to reveal the unborn baby's gender, but staff at Los Angeles boutique Petit Tresor claim they dropped big hints it will be a boy.
Sources at baby store tell CelebTV that everything the couple purchased during a recent shopping spree was blue.
The couple's shopping list reportedly included a bib with "hunk" written on it, and a number of other clothes.
A salesperson that helped the couple said, ��They made it very clear that it was a boy.��
