Jennifer Aniston felt "married for so long" before she actually did tie the knot with husband Justin Theroux.

The couple have been wed for eight months but the Cake star insists she and Justin, 44, were already living like a very happy husband and wife before she said "I do".

In an interview with the April issue of Harper's Bazaar magazine, she said: "We felt married for so long. Married life is so normal and fun and not much different."

Jennifer - who was previously wed to Brad Pitt - has praised her man for making her so happy and she says she's never met anyone who could make her laugh as much as the Zoolander No.2 scriptwriter.

And the 47-year-old screen beauty believes the constant laughter in her life helps keep her young at heart.

She shared: "I'm lucky because Justin is the funniest person I've met, and we make each other laugh. Laughter is one of the great keys to staying youthful."

Aniston insists she's never felt healthier since she reached her 40s and she also feels wiser than at any other point in her life.

She said: "I feel better in my 40s. Not only do you feel better in your body physically, but you're mentally better.

"Because, say, in your 20s, you didn't know s**t. For me, in my 30s, I was just trying to figure it all out. Then when you hit 40, you're like, 'Oh, OK. I got this.'

"There are women who've hit 50 who are stunners, like shocking. We just take better care of ourselves."
