Jennifer Aniston and Justin Theroux are having marriage problems. According to In Touch Weekly, the couple, who haven't even been married for a year, are already living separate lives and has even put off their plan for adoption.

"Justin's apathetic when it comes to marriage," a friend told the tabloid. "He's a guy who was meant to be single. Jen's starting to realize that, too." According to the source, Jennifer and Justin "remain at complete odds over everything, from how much time they spend together to where they should live. She loves LA, he'll take Manhattan."

The source said that the distance between Jennifer and Justin has been growing, and now Jen's dreams of motherhood have been put on hold too. "She and Justin were halfway through the process of adopting twins - a boy and a girl - and were hoping to bring the kids home in the next couple of months, but their plans came to a halt when they started having problems," the source claimed. "She'd even built a nursery in her Bel Air home."

"They've been married for barely seven months - and it’s already over," the source continued, "It's heartbreaking."
