Angelina Jolie and Brad Pitt are trying to save their failing marriage by spending time with their six children in London this spring, Hollywood Life reported Thursday. Jolie and Pitt, one of Hollywood’s most popular couples, are reportedly “living separate lives” and are on the verge of a divorce because of their busy schedules.

The celebrity couple, together for over 10 years, has been facing divorce rumors lately. However, Jolie and Pitt have been spotted together on several occasions,  dismissing reports about their marriage troubles. But this time, their work has reportedly taken toll on their relationship and the two do not want their children suffer because of it.

“The past few months have been tough on Brad and Angie because they’ve both been very wrapped up in their own projects. They went from doing ‘By The Sea’  together and having all this time as a family to spending the majority of their time apart. That is hard on them. Whenever they have to spend too much time apart, it causes tension in the relationship,” a source told Hollywood Life. “They both want to make sure the kids get enough time with at least one of them around so they argue about that. They both know they need to come back together and have more time as a family unit. They’re looking forward to moving to London together this spring,” the insider told the entertainment website.

Apart from their busy work life, reports also said that 40-year-old Jolie has “dark demons,” something that Pitt is losing patience with.

“Some of her issues force her to retreat into isolation and pull away from Brad and the kids. It is impossible to be entirely free from who she once was. Angie has some serious dark demons that have never entirely let go and it is still affecting her life and marriage,” a source reportedly said. “[Pitt] feels he has been more than patient with Angie, but his confidence in their happiness is wearing thin. It can be really hard on him,” the source reportedly added.

The couple starred in the Jolie-directed “By The Sea” released in late 2015, which is a romantic drama about a married couple that has grown apart. The two are parents to Maddox, 14; Pax, 11; Zahara, 10; Shiloh, 9; and twins Vivienne and Knox, 7.
