Christina El Moussa posts somber Instagram message

There is one person that is making Christina El Moussa smile amid her split from husband Tarek. The "Flip or Flop" star posted an Instagram video of her 15-month-old son Brayden. She tagged her estranged husband in the post.

"Even on my roughest days he always brings a smile to my face.#BraydenJames you make our lives complete," she wrote.

The couple announced last week they were ending their seven year marriage, months after police were called to their home over what the couple called an "unfortunate misunderstanding."

The "Flip or Flop" stars told FOX411 the May incident prompted them to seek counseling, and they've decided to separate while evaluating the future of their marriage. The added that they plan to continue their professional life together.

It was also confirmed to FOX411 that Tarek dated his children’s nanny after he quietly split from his wife in September. The nanny and Tarek are no longer together.

And just last Thursday, Christina and Tarek were spotted grabbing coffee together.

Even though the couple are separated, they are still working together on their hit HGTV show.

"HGTV is currently airing episodes of 'Flip or Flop' and the series will continue production as scheduled," the network has stated.
