Pete Wentz cradled wife Ashlee Simpson-Wentz‘s growing belly as they hitched a ride on Sunday at the American Century Championship. The event was held at the Edgewood golf course on the shores of Lake Tahoe, NV. Musicians Pete, 29 — who is "becoming my dad" — and Ashlee, 23, will welcome their first child this fall.
