It's my job to love Brad Pitt: Angelina Jolie

London: Actress Angelina Jolie considers it her "job" to love husband Brad Pitt.

The "By The Sea" director and actress, who married her co-star in the film in August 2014 after 10 years together, admits they don't always see eye-to-eye, but believes "big fights" make their relationship stronger.

"It strengthens a relationship if you can pass those big fights and those big things where you really come head-to-head.

"As much as we can argue and fight, and we all have our challenges, at the end I say, 'My job is to love him.' "

The Oscar-winning actress, 40, thinks the 52-year-old heartthrob gets better with age and is looking forward to growing old with him.

"I'm more interested in his 50-year-old self than his 40 year-old-self. And then you look forward to even more years together. Brad and I are fortunate because we see the beauty in each other's changes."

The couple have six children, Maddox, 14, Pax, 11, Zahara, 10, Shiloh, nine, and seven-year-old twins Vivienne and Knox.
