Christina Haack didn't bother to let at least one of her baby daddies know that she was going to be getting married for a third time.
According to her first husband and Flip or Flop co-star, Tarek El Moussa, he found out about his ex's engagement to Joshua Hall like the rest of the world did – on the internet.
"We just saw, but congratulations!" he told People when asked if he and his fiancée, Heather Rae Young, had heard the news.
"Wow, awesome! We just want nothing but happiness for [Christina and Josh] and nothing but happiness for the kids," added the Selling Sunset star, who often refers to herself as the El Moussa kids' "bonus mom."
"We're looking forward to the next chapter of everyone's lives," she said.
In addition to learning of the engagement news, Tarek also just found out that he has COVID-19.
His rep confirmed that the Flipping 101 star recently tested positive, and even though he has tested negative several times since then, he and Heather's respective television shows will halt production out of an abundance of caution for all those involved.
Tarek is reportedly not experiencing any symptoms and will be quarantining at the home he shares with his wife-to-be, who has so far only tested negative.

It's unclear where El Moussa and Haack's two children – 10-year-old daughter Taylor and 6-year-old son Brayden – will live during this time, given that Christina is seemingly still in Mexico with her new fiancé.
Christina also shares a 2-year-old son named Hudson with her second husband, Ant Anstead. Their divorce was finalized this past summer, and he has since moved on with Oscar-winning actress Renée Zellweger.
After weeks of teasing the media by posting and quickly deleting photos showing a massive diamond on her left ring finger, the Christina on the Coast star finally confirmed she was engaged on Monday.
She and Josh Hall – a realtor from Austin, Texas – started dating in the spring but did not go public with their romance until shortly after her split from Ant was officially legal.
At first, Christina played coy – posting to Instagram several shots of her with her boo, enjoying a romantic dinner on the beach. They locked lips and took selfies, one of which showed a sparkler on Haack's right ring finger. She captioned the images using the following emojis: a red heart, an eternity symbol, a lock, a key and a diamond ring.
Hours later, she took to her Instagram Story to be more overt. After sharing a closeup video showing off her new bling (which was now on her left ring finger), Haack posted a snap of the couple's view from their posh Cabo resort and wrote, "Full moon vibin' with my fiancé."
She also changed her bio to include a diamond ring emoji and the name of her future husband.
