Pete Wentz's management thought he would die at 27. The 29-year-old rocker - who is the bassist in Fall Out Boy - has revealed record company bosses feared he would follow in the footsteps of rock legends Janis Joplin, Jim Morrison and Kurt Cobain by dying at that age because he was taking so many drugs.

He said: "I spent most of the year I was 27 toxic, just completely over-medicated. I was stoked to make it past 27."

Ashlee Simpson threw a "white-trash" themed birthday party. The pregnant singer, who is married to Fall Out Boy rocker Pete Wentz, celebrated turning 24 with a fancy dress bash at her parents' Los Angeles home last weekend.

One guest revealed: "It had a white-trash theme. Ashlee wore Daisy Duke hot-pants and platform flip-flops with a bathing suit and a fake tattoo around her belly."

Pete Wentz is worried his baby won't like his music. The Fall Out Boy rocker - whose wife Ashlee Simpson is due to give birth in October - is currently in the studio working on the band's third album and says the record is bringing extra pressure because he wants his impending new arrival to like his songs.

He said: "This is the first record we've made that I'll be able to play for my baby. That's a lot more pressure than whatever my record label thinks of it."

Ashlee Simpson is expecting a baby boy. The singer's husband, Fall Out Boy rocker Pete Wentz, says the couple are almost certain that they know the gender of their unborn first child.

He said: "We know with 90 per cent accuracy that it's a boy, and our due date is around Thanksgiving."
