After HGTV's Flip or Flop stars, Tarek and Christina El Moussa, announced their shocking split on Monday a source said that they have actually been living apart since May and have been dating other people.

It was the split no one saw coming and now the news that no one would have guessed was revealed to People. According to the source, Tarek and Christina split up last May after their explosive altercation involving a gun and their young children, Taylor and Brayden, have been staying with their mother. The insider also said that following the breakup, Tarek has been seeing other women and Christina has become romantically involved with a "fellow design industry professional."

The couple did not release a statement announcing their separation until Dec. 12. They did, however, briefly discuss the May incident that led to a dozen police officers and one helicopter descending on their property in search of Tarek, who ran out of the home with a gun.

“Like many couples, we have had challenges in our marriage,” the statement read. “We had an unfortunate misunderstanding about six months ago and the police were called to our house in an abundance of caution. There was no violence and no charges were filed.”

At this time HGTV plans to continue airing episodes of Flip or Flop.
