Heather El Moussa put work into cultivating a relationship with husband's ex-wife, Christina Hall
'The Flip Off' star explained to Fox News Digital that time has helped heal wounds between the friendly exes.
Heather Rae El Moussa won't be mom-shamed.
The HGTV star, 37, is married to Tarek El Moussa, and the couple share a son, 1-year-old Tristan. She's also stepmother to the two children he shares with ex-wife Christina Hall – Taylor, 14, and Brayden, 9.
On Christmas Eve, El Moussa shared a series of photos of herself with Tarek, Tristan and Brayden, as well as a number of other people at what appeared to be a holiday party. In the photos, she was wearing a revealing red dress made primarily of fishnet and lace.

"Dress looks like more for the bedroom!" one person commented, along with a crying emoji.
"The dress? Really and as a mother of a little boy!" another person wrote.
Another comment read, "The dress is not appropriate. Your [sic] a mother now," and to that, El Moussa fired off a response.
"So because I'm a mother I can't wear a pretty dress that makes me feel beautiful?" she wrote, per People. "What does that have to do with anything? I'm still a human and my name is heather I'm not just a mother. Choose joy."

The "Selling Sunset" star and Tarek mainly film together, but they sometimes film with Christina, which has been "very competitive," according to the "Flipping 101" star.
"I think people are very excited about 'The Flip Off' because, obviously, you have exes working together again after they were on 'Flip or Flop' for so long," Heather noted. "It's been like a fun, friendly competition."
