Tarek and Christina El Moussa have taken the next step in their estrangement.
Tarek has filed for divorce from his wife and Flip or Flop co-star, ET can confirm.
People was first to report the filing.
The HGTV couple announced their separation in a joint statement released in December, where they revealed that they had split following a heated fight that lead to the police getting called out to their Orange County, California, home back in May.
"Like many couples, we have had challenges in our marriage," they said in a statement to ET. "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."
Tarek and Christina went on to say that they "sought out counseling" but have decided to separate to reevaluate "the future of our marriage."
The former couple, who tied the knot in 2009, have two children – a 1-year-old son, Brayden, and a 6-year-old daughter, Taylor.
The couple told ET in December that, during their separation, "we are committed to our kids and being the best parents we can be."
Over the holiday season, the proud parents made sure to spend time with their children and even posted adorable Christmas family photos. However, the estranged couple did not pose together.
Tarek has been spending a ton of time with his cute tots since the start of the new year, sharing a number of adorable photos to Instagram.
Today signifies they end of another year. It's a time where we all reflect on our own personal journey. Looking back we must ask ourselves what we did right and what we did wrong. It's a time to look back and ask ourselves if we took advantage of the year we will never get back. For me... 2016 was the biggest defining year of my life. It was a year that will change the destination of my life and I'm ready for the ride. The crazy ride of 2016 taught me so much about myself. Today, going into 2017, I've learned i'm much stronger than I ever thought possible and the lessons I learned in 2016 will stay with me through the rest of my life. I truly believe in all these words and I urge everyone to look back and ask yourself what lessons can you take from 2016 to make 2017 the best year ever!! HA
Christina, meanwhile, shared a photo mosaic of Brayden and Taylor, along with a lengthy caption reminiscing about her "crazy year of highs and lows."
"A lot of things have changed but one thing will always remain a constant in my life and that is the love I have for our children," she wrote. "Their genuine happy spirit is always the light at the end of the tunnel." Check out the video below for more from Christina's contemplative New Year's message.
