Kate Moss has yet to walk down the aisle with her fiancé, Kills guitarist Jamie Hince, but she’s already trying for baby No. 2. “She wants to have another child, and they’re trying to get pregnant,” a source close to Moss told us. Moss is mom to Lila Grace, 8. Fashion royalty is gearing up for the July 1 nuptials in England, and some are flying from New York as early as this weekend. Moss has been mum on who is her wedding dress designer, with reports that she turned to friend John Galliano, but fashion types are buzzing that she’s chosen Alexander McQueen. Moss’ rep didn’t get back to us.
