"ET" has the real story on the Ashlee Simpson twins rumor! Ashlee's publicist confirms that Simpson and husband Pete Wentz are not expecting twins.

Rumors on the Internet spread after Pete's friend, hip-hop artist Tyga, allegedly told reporters at a pre-VMA barbeque that the couple was expecting twins and they couldn't be happier.

Pete's band, Fall Out Boy, is up for a VMA tonight for Best Rock Video for their cover of Michael Jackson's "Beat It."
