Justin Theroux always under pressure

Justin Theroux always feels a "hum of pressure".

The actor is engaged to Jennifer Aniston and ever since they announced the news in 2012, there has been speculation about when they will tie the knot.

Despite this, the 43-year-old doesn't worry about hurrying Jennifer down the aisle.

"There is this hum of pressure that - I can't stress enough - I just don't pay any attention to," he revealed to Australian magazine TV Week.

"But I am not going to let a tabloid tell me what to do... I'm not going to watch them tap their watch. What the hell are you telling me to do'

"We're just doing our own thing. We are completely happy, obviously, but we're not on anyone else's timeframe."

The star added his life has been "enriched" since finding love with the 45-year-old actress.

Alongside planning a wedding, Justin is focusing on his career. He appears in new show The Leftovers, a drama that sees people mysteriously vanish off the face of the Earth.

"I've lost good friends, I've lost family members. Then there's the obvious comparison, although I'm reluctant to compare a TV show to September 11. That event was, as a New Yorker, the first and hopefully last time I'll feel that sort of collective grief. It made that big city feel incredibly small," he said.

It was work that brought Jennifer and Justin together, with the stars falling for each other after filming 2012 comedy Wanderlust together.

The actor sometimes marvels at his chosen job.

"My career has followed no particular path. As I'm sure you're aware, I have the dumbest career in the world as far as, 'Yeah, I'll do that.' I've really guided myself on what is going to be the next fun thing to do, I don't think of it in terms of, 'Will this be smart for my career'" he admitted.
