Jennifer Aniston and Justin Theroux’s low-key anniversary

Jennifer Aniston and Justin Theroux enjoyed a low-key anniversary celebration.

The couple marked a year since they tied the knot in a secret ceremony on August 5, and the 44-year-old actor flew to Los Angeles from Australia, where he has been working on the upcoming season of ‘The Leftovers’, to ensure he would be with his wife on their special day.

A source told People magazine: "Justin flew from Australia to LA to spend their anniversary week with Jen.

"They relaxed at home, had dinner with friends and had a small anniversary celebration at home."

While the ‘Cake’ actress adores being married to Justin, she previously insisted she had felt like they were husband and wife for a long time before they tied the knot.

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."

The former ‘Friends’ star has 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."
