Actor Aaron Johnson, 21, and director Sam Taylor-Wood, 44, expecting second child

Kick Ass star Aaron Johnson and filmmaker (and soon-to-be wife) Sam Taylor-Wood are expecting their second child together. Johnson is 21, while his fiancee is 44.

The two met on set of Johnson's movie, Nowhere Boy, a John Lennon biopic in which Taylor-Wood was directing. The 23-year age difference doesn't seem to be a problem, though, because the pair are looking forward to another child together.

Johnson and Taylor-Wood already have a one-year old daughter, Wylda Rae, and Taylor-Wood has two other children from a previous marriage to art director Jay Jopling. The two got engaged after the birth of their daughter. They have been together for three years.

Johnson has shot down scrutiny of his relationship in the past, telling the media, "I'm an old soul, and she's a young soul."

The actor will next be seen in Oliver Stone's Savages.
