Jennifer Aniston and Justin Theroux are hit by reports that the couple's relationship is on shaky grounds. Brad Pitt's former wife is allegedly upset with their "long-distance" marriage.

According to a report in Life & Style, Aniston flew to Berlin where Theroux is filming his new movie, Mute, to save their relationship. A source said: "She basically hunted him down for the make-or-break talks. She's fed up with their long-distance Skype-every-other-day marriage, his refusal to settle down in L.A. and his choosing his career over her."

"Jen's over it. She explained that she was tired of having an absentee husband. She really had it out with him during a days-long conversation. She was alternating between anger and tears. She just hopes her Hail Mary attempt works," the insider added.

The We're The Millers actress and Theroux, announced their engagement in August 2012 after dating for 15 months. The former Friends star and the 45-year-old actor exchanged vows in a secret ceremony at their $22m Bel Air mansion on 5 August 2015.

Aniston had gushed about Theroux to Women's Wear Daily. She said: "I commend him for his courage. This is not normal for him. He's so graceful and utterly kind and golden."

"It is amazing. He's just so beautiful and handsome to me, and I love that his eyeballs are so beautifully captured because those eyes just knock me out every day," she went on. "He just gets better every year. He's just like a lost gem in the sand, and he's just always been there and been brilliant, and now this is just in a different light."
