Aaron Taylor-Johnson doesn't notice the age gap between him and his wife.

The 'Nowhere Boy' star refuses to ''engage'' in any talk about the difference in age between him and his wife Sam Taylor-Johnson, who is 23 years his senior.

He said: ''I don't engage with [talk about the age gap]. At an early age when I saw articles, it just f***ed me up ... What does it even f***ing matter about our age? I never noticed it when we fell in love with each other.

''And 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.''

The 24-year-old actor wed the 48-year-old director in 2012 and says he had no issue with getting married at an early age because he was keen to have children with Sam as soon as possible.

He added to The Times magazine: ''I met Sam and I knew I wanted to be with her. And it got clearer, each step...

''I wanted kids, we had kids and I was really into that, taking time off and involving myself in the bubble of her pregnancy.''
