Pete Wentz quashed rumors that he and wife Ashlee Simpson are expecting twins at yesterday’s MTV VMAs.

At the awards show he told Us magazine,

“It’s going to be a big disappointment when it’s only one!”

Wentz mistakenly referred the unborn child as “them” during a radio interview a few months back.  He later stated that he had fudged up the facts.

“[I was] waaaaay wrong.  I totally misspoke ’cause we dunno if it’s a boy or girl. I try to speak vaguely, and I totally blew it on this one.”

Ashlee is due at the end of October.
