Jennifer Aniston is at a career "crossroads."

The 47-year-old actress may have a huge selection of highly successful movies under her belt, as well as a long stint as Rachel Green in the sitcom 'Friends', but she has admitted she's starting to get bored of her life in front of the cameras.

She explained to Marie Claire magazine: "This is a time when I'm not completely sure what I'm doing. I'm at this sort of crossroads trying to figure out what inspires me deep in my core. What used to make me tick is not necessarily making me tick anymore ... The most challenging thing right now is trying to find what it is that makes my heart sing."

Jennifer's priorities shifted when she married Justin Theroux last August and she's adamant any role she's offered from now on will have to be worth it if she's to tear herself away from her spouse, who is currently in Australia shooting 'The Leftovers'.

She said: "You have to be so madly in love with it and think, I will be so upset if I don't go and play this person...Especially these days, with Justin in Melbourne. It has to be worth it."

The couple began dating in May 2011, got engaged just over a year later and tied the knot at their Bel-Air estate in August 2015, and, although they're still in the honeymoon period, the brunette beauty knows Justin, 45, is the "right person" for her.

She explained: "Why is he the right person for me? All I know is that I feel completely seen, and adored, in no matter what state. There's no part of me that I don't feel comfortable showing, exposing. And it brings forth the best part of myself, because I care about him so much. And he's such a good person. It hurts me to think of anything hurting him."

Jennifer is perfectly happy in her relationship with Justin, but she felt the need to fight back against body shamers and those who criticise her decision not to have children and her highly public divorce from Brad Pitt in 2005 in her powerful opinion piece, which she penned in July for the Huffington Post.

She said of her gripping piece: "My marital status has been shamed; my divorce status was shamed; my lack of a mate had been shamed; my nipples have been shamed.

"It's like, 'Why are we only looking at women through this particular lens of picking us apart? Why are we listening to it?' I just thought: I have worked too hard in this life and this career to be whittled down to a sad, childless human."
