Pete Wentz worried kids will get bipolar disorder

Fall Out Boy bassist was diagnosed with the disorder when he was a teen

Rocker Pete Wentz is worried his children will inherit bipolar disorder.

The Fall Out Boy bassist, who has six-year-old son Bronx with ex-wife Ashlee Simpson and five-month-old son Saint with girlfriend Meagan Camper, was diagnosed with the manic-depressive disorder when he was a teenager.

While he credits his children for helping him to get his life under control, he fears his boys might experience the same "highs and lows" in the future as he has.

When asked about it, he said: "Yeah, that's one of the things I've worried about."
