Pete Wentz hints at twins pregnancy

Pete Wentz has hinted that wife Ashlee Simpson may be expecting twins.

The Fall Out Boy rocker referred to his unborn child as "them" during a radio interview, sparking rumours that Simpson may be carrying more than one child.

"We've been keeping a book so far, like a journal for them - for them when they're, uh, born," said Wentz.

The musician also revealed that he wanted to know the sex of his child because he was already preparing gifts.

He commented: "I'd like to know the sex of the baby. It would be a bummer if you bought a boy a bunch of pink stuff!"

Wentz and Simpson confirmed the pregnancy last month.
