Pete Wentz and Ashlee Simpson Open Chicago Bar

Fall Out Boy bassist—and expectant father—Pete Wentz was back in his hometown of Chicago Tuesday night to celebrate the opening of the rocker’s new bar, Angels & Kings.

Ashlee Simpson, Wentz’s new wife, stood by her man on the red carpet before the event, flaunting a growing belly bump. Simpson-Wentz, 23, clearly isn’t letting pregnancy cramp her style. The singer rocked sky-high nude patent pumps, along with a black jersey mini dress.

The event doubled as a hometown birthday celebration for Wentz, who turned 29 on June 5.
