Johnson, 21, and Taylor-Wood, 44, made headlines last year with their 23-year age difference, but the actor has brushed off the large gap. "I've got a wonderful woman," he said last spring. "I'm an old soul, and she's a young soul."  The pair met on the set of her 2009 directorial debut Nowhere Boy, in which Johnson played a young John Lennon. Taylor-Wood also has two daughters from her first marriage to art dealer Jay Jopling.
