Eddie Vedder Yields to Marriage

Pearl Jammer swaps vows with longtime baby mama, model Jill McCormick, Sunday in Hawaii

Eddie Vedder has gone from grunge to groom.

The Pearl Jam frontman tied the knot with longtime girlfriend Jill McCormick in Hawaii on Saturday in a ceremony attended by the likes of Sean Penn (who featured Vedder's music on the Golden Globe-winning Into the Wild soundtrack) and easy-going rocker Jack Johnson.

The 45-year-old Vedder got engaged to the 32-year-old model in December of last year while the two were in Washington, D.C., for the Kennedy Center Honors gala, where Vedder offered a stirring tribute to honoree Bruce Springsteen. The pair have two daughters, 6-year-old Olivia and Harper Moon, who turns 2 on Thursday.

It's the second matrimonial go-around for Vedder, who was previously hitched to Hovercraft cofounder Beth Liebling from 1994 to 2000.
