Last week was splitsville for celebs, but one couple who know the secret to a happy marriage are Jennifer Aniston and Justin Theroux.

Jen’s ex-husband Brad Pitt made headlines last week when Angelina Jolie filed for divorce from him, but all is still rosy in the former Friends star’s relationship and Justin explained why.

Speaking to Entertainment Tonight as he promoted his film The Girl On The Train, Justin said of his wife: “We appreciate each other’s sense of humour, we respect one another and we get along.

“I know it sounds simple – but it’s true!”

Asked whether we’d be seeing him starring opposite his famous missus any time soon, Justin said: “I mean we would love to, of course. You know, it’s that thing of I have been working for the last three years on the TV show (The Leftovers) which has prevented me from working on anything else.

“And it has to be the right thing and something the both of us want to do, you know. We’ll see.”

Jennifer and Brad were married from 2000 to 2005, but split soon after he met Angelina on the set of film Mr And Mrs Smith.
