Hollywood power couple Angelina Jolie and Brad Pitt are reportedly having trouble in their married life.

According to InTouch magazine, Jennifer Aniston's former husband and the 40-year-old Academy Award winning actress will "tell the world" that they are divorcing by the end of the year.

"He's the one who's calling time on their marriage. He's told Angie they're over," an source told the publication, according to Hollywood Life. "He's beyond miserable and wants out."

Last year in August, the couple who are already parents to six children, three of whom are biological and the rest adopted from Cambodia, Vietnam and Ethiopia, got married in France.

"He says she's controlled him from day one of their relationship," the insider added. "Although he liked her taking charge at first, he's come to resent the power he's allowed her to have over him."

According to the magazine, Jolie and Pitt will part ways after the release of their upcoming movie, By The Sea.

The film has been written and directed by the Maleficent actress and is the first time she and the Moneyball star have co-starred in a film since the famous 2005 action drama, Mr and Mrs Smith.

"It's Angie's most personal film, and it means the world to her," the source continued. "She's begged Brad to hang in until after it hopefully is the hit she believes it's going to be. He's reluctantly agreed," the source claimed.
