HITCHED: Sam Taylor-Wood and Aaron Johnson

Kick-Ass star Aaron Johnson, 22, and fashion photographer-turned-director Sam Taylor-Wood, 45, who met Johnson when she cast him for the title role of her 2010 biopic about John Lennon, Nowhere Boy, got married on Thursday in Sommerset, England, after a three-year engagement.

Taylor-Wood and Johnson have two daughters together — Romy, 5 months, and Wylda, 2, reports People. Taylor-Wood also has two daughters from her previous marriage with ex-husband Jay Jopling.

The couple's romance has been the topic of media attention, in light of Johnson and Taylor-Wood's 23-year age gap, but they have generally publicly shrugged off the matter. "I'm an old soul and she's a young soul," Johnson once said of his relationship with Taylor-Wood. "We don't see an age gap, we just see each other."

Both stars changed their names to Taylor-Johnson after the nuptials. Johnson will next appear in Oliver Stone's Savages, followed by Joe Wright's Anna Karenina, in which he will play Count Vronsky.
