The 45-year-old actor is hugely proud of his "amazing" actress wife and insisted he is delighted to be described as her husband.

He told The Sunday Times Magazine: "It doesn't really get under my skin. It's just one of those things that's a shorthand for describing who I am.

"[Jennifer] is a proper badass. She has lived through a lot of bulls**t. Many people would have crumbled under some of the stresses that have been put on her. I'm very proud of her for that, for the way she handles herself. So in a weird way it's an honour to stand behind her. Truly, in that sense, she's amazing."

The couple had been friends for years but only started dating after filming the movie 'Wanderlust' together in 2011 and Justin would jump at the chance to work with Jennifer, 47, again.

He said: "It'd be more convenient …We could see each other more. Would it be weird? I don't know. If it was the right thing. Or something I wrote that she would act in. We're not competitive."

Justin sometimes finds it hard to deal with public interest in his and Jennifer's relationship and he praised his spouse for a recent op-ed she wrote for the Huffington Post about her frustration with speculation about her personal life.

He said: "She's similar to me - she doesn't pay attention to it unless she has to. But there's definitely times when your privacy is invaded. Areas of your personal life that are yours to discuss among yourselves and your friends and family shouldn't be a topic for national debate.

"She addressed it beautifully in her HuffPost piece. I was very, very proud of her for writing that. It was very well written. She expressed herself beautifully."
