By her early twenties, Hansen’s life was a blur of international travel, posing and partying. She met Keith Richards at Studio 54 on her 23rd birthday and married him four years later. They have two children, Theodora, 27, and Alexandra, 26. “Marriage definitely gets easier over time,” Hansen says. “Sometimes it’s hard to remember why you got together in the first place. It’s a struggle, but it’s great when it works.”

Determined to move on, Hansen launched a line of handbags last year called Hung on U, slouchy in soft-as-butter leathers, mesh and exotic skins and sold on both HSN and HungonU.com. Although Hansen calls it “my little business thing,” she’s clearly enjoying the creative outlet.
