text: It's a relationship that's fascinated the public and come under intense media scrutiny for years. Aaron Taylor-Johnson was just 19 when he met wife Sam, then 42, on the set of Nowhere Boy in 2009 in which he played the young John Lennon and she directed him. Six years, one marriage and two children later, the Hollywood actor has revealed that he doesn't even notice the age gap because of his mature nature - he is so grown up that friends of the couple call him Benjamin Button after Brad Pitt's character in the 2008 film The Curious Case of Benjamin Button, who ages in reverse. Scroll down for video . Aaron Taylor-Johnson, 24, and wife Sam, 48, at the premiere of Avengers: Age of Ultron on April 13 . Alexander McQueen printed silk-chiffon dress . Available at Net-A-Porter!

Sam Taylor-Johnson wowed at the Avengers Age of Ultron world premiere in LA alongside her Gucci-clad hubby. She wore a pink, feminine, floral Alexander McQueen frock, which boasted a soft and ethereal silhouette with its multiple layered ruffles and button detailing that captured our hearts.

Depsite being a toyboy, Taylor-Johnson says friends liken him to Brad Pitt's character in The Curious Case of Benjamin Button, in which Pitt ages in reverse . A recent Instagram image shows the couple clearly in love six years after they first met . In an interview in Saturday's Times magazine the co-star of the latest installment of Disney's superhero blockbuster Avengers: Age of Ultron says: 'I don't notice it now - we just instinctively gel ... People who know me call me Benjamin Button - they think I'm an old soul and she's a young soul.' Taylor-Johnson says he fell in love with Sam, the most commercially successful female film-maker in history after she directed Fifty Shades of Grey, which was released in February, on the first day they met on the set of Nowhere Boy in 2009. After a whirlwind romance, the pair announced their engagement at the film's premiere later that year. They married at Babington House in Somerset when Taylor-Johnson was 20, a move he says made 'perfect sense'. He tells the magazine: 'I knew I wanted to be with her. I wanted kids, we had kids and I was really into that, taking time off and involving myself in the bubble of her pregnancy.'

The couple's first daughter, Wylda Rae, was born in July 2010 followed by Romy Hero in January 2012. The family now lives in Los Angeles with Sam's daughters Angelica, 17, and Jessie Phoenix, eight, from her first marriage to the art dealer Jay Jopling, and the couple take on one project a year each so one parent is always at home. Aaron, who grew up in High Wycombe, Buckinghamshire, has been acting since the age of six when he starred in a Persil advert. When he was 12 he appeared in Hollywood action comedy Shaghai Knights, and when he was 15 he worked alongside Edward Norton in The Illusionist. Taylor-Johnson says he was a 'self destructive teenager struggling with success' before he met Sam. But after the two got together, she quickly became his best friend and a stable influence in the notoriously fickle Hollywood. He and Sam now focus most of their time on being parents, with school runs and extracurricular activities taking up the bulk of their days. They have a rule that they are only allowed to take on one project a year, meaning that someone is always around for the children. And although looking after four children at the age of 24 might seem like a hard task, Taylor-Johnson says he has never been happier. He told the newspaper: 'Being a father has been the happiest time of my life - it's what I live for, what I love doing - I have a real reason why I'm here, I'm not as proud of my acting; it's a job that I do ... I'm grateful, but I don't live for acting.'
