Ashlee Simpson & Pete WentzAshlee Simpson-Wentz and Pete Wentz have sparked rumours that they’re expecting a baby boy after preparing a very blue baby registry list.

A source from celebrity-favourite baby boutique Petit Tresnor told OK magazine: “They made it very clear that it was a boy. Almost everything [they picked out] is blue.”

The list included a handful of baby rocker tshirts and bibs embroidered with the words ‘loved’, ‘yummy’ and ‘hunk’.

The baby, the newlywed couple’s first, is due in the autumn. Ashlee’s older sister Jessica Simpson recently revealed that Ashlee is “popping” and her baby bump is “so cute!”.
