Katrina Bowden accessorized her white Amsale gown at the Screen Actors Guild Awards with a gorgeous new accessory—an engagement ring! Her rocker fiancé, Ben Jorgensen of the band Armor for Sleep, popped the question just the night before in a suite at the Four Seasons Hotel in Los Angeles. “It was a huge surprise,” the 30 Rock star told InStyle.com. “We’d talked about it, but I didn’t know when it was going to happen.” And the sparkler—a cushion-cut with two princess stones on each side—was perfect for her taste: “It’s a beautiful ring. I like antique, gorgeous rings.” Between this and the white dress—she already looks ready to walk down the aisle!
