One of Hollywood’s most famous couples, Ben Affleck and Jenifer Garner, is reportedly heading towards a divorce, just weeks before their 10-year anniversary in June. They are rumored to have been separated for over a month.

“They’re already separated,” a source told OK! magazine on Wednesday, adding: “Ben wants the official statement to come out a few weeks before their 10th anniversary June 29 — which he hopes will give enough time for the news to die down by the time he has to promote Batman v Superman (Dawn of Justice) and the other movies he has coming out next year.” Affleck, who has acted in critically acclaimed movies like "Argo" and "Goodwill Hunting," is also set to appear in "Justice League: Part One," which is slated for a 2017 release.

According to a report by Inquisitr, the divorce may be worth $150 million.

Radar Online reported that while Garner was seen having lunch with a friend at Sant Ambroeus in Manhattan on May 13, the "Gone Girl" actor was seen gambling in Las Vegas around the same time. Their three children, Violet, 9, Seraphina, 6, and Sam, 3, were back in Los Angeles while Affleck returned to them after a couple of hours. 

“Jen and Ben have had many fights this year over his increased gambling,” the source told OK! magazine. Last May, the "Batman" actor was banned for life from playing Blackjack at the Hard Rock Casino & Hotel in Las Vegas because he was counting cards. While Affleck maintained that Garner had never been angry at him for gambling, some media reports said that Affleck’s gambling may have been a problem for the couple.

The Radar Online report added that on Garner’s birthday on April 17, Affleck was seen on a trip alone to Canada, without his wedding ring. The couple has reportedly not been spotted together for a month. Another report by Radar Online said that Garner, who has starred in "Dallas Buyers Club," "13 Going On 30" and "Pearl Harbor," temporarily moved to Montreal on April 29.

Garner has “been preparing herself emotionally for a divorce for some time,” the source told OK! magazine, adding that she is “miserable” due to the split. 

“This is a very difficult time for her,” a neighbor of Garner’s sister, Susannah, told OK! magazine, adding: “Everyone needs to stop talking about it.”

Last week, Garner had given an interview to Yahoo! Parenting and said: “You just go on a ride together because you don’t know who you’re going to be when you first have a baby and you don’t know who [your partner] is going to be. You have to just hang in there while you figure it out — and have a lot of patience for each other.”
