It’s probably not a coincidence that Alicia Keys and her husband, Kasseem “Swizz Beatz” Dean, are wearing matching pants. His: expertly tailored and trim, skimming his sneakers just so. Hers: a sexy waxed denim that hugs her in all the right places. Both are the color of a well-made cappuccino. They’ve agreed to be interviewed together over dinner, a double date of sorts. It’s one of those novel ideas cooked up by magazine editors, but Keys, who seems more open now than she’s ever been, was keen to participate. And what better way to convey closeness than with his-and-her trousers.
