The Flip Or Flop co-host Christina Haack is engaged to Joshua Hall, but it turns out she didn't tell either of her ex-husbands ahead of announcing the news publicly. Her exes found out along with everyone else in the world. Fans are curious to find out how Tarek El-Moussa and Ant Anstead heard the news about the engagement and how they reacted to it.

After a bit of speculation, the Christina On The Coast star confirmed her engagement on Monday, September 20. This comes three months after her divorce from Ant, with whom she has a 2-year-old son, was finalized. Meanwhile, the Celebrity IOU: Joyride host is currently dating actress Renée Zellweger. Christina's first husband, Tarek, the father to her two older kids, is set to marry Selling Sunset's Heather Rae Young soon. Tarek and Christina still co-host together years after their divorce. But while Tarek and Ant have also moved on, how do they really feel about not learning the big news from Christina herself?

A source revealed to Us Weekly that both Ant and Tarek both found out about Christina's announcement on social media. As for their reaction, the source said, “They’re both happy for her and wish her the best." Speaking to PEOPLE, Tarek confirmed he'd only just found out. He sent congratulations, while Heather called the news "awesome," adding that they were "looking forward to the next chapter of everyone's lives." It couldn't have been a total shock to the pair, as Tarek and Heather were previously asked about the rumors that Christina's diamond ring meant she was engaged. The 40-year-old then praised the relationship between his ex-wife and her new fiance.

Considering Tarek and Ant discovered news of the engagement at the same time as everyone else, it looks like they aren't as close to Christina as they thought. Soon after Christina and Josh went IG official, news broke about a major fight between her and Tarek on set. After the news of the fight, reports suggested Christina and Tarek's cordial exes act was entirely fake. Attempting to leave that drama in the past, Tarek recently admitted he regrets the fight. But the lack of a heads up from his ex indicates that it may not be water under the bridge.

Whether or not they really are cordial, Christina and Tarek are set to continue co-hosting Flip Or Flop for the near future. In the meantime, Tarek and Heather's nuptials will be featured on Selling Sunset season 4Longtime fans hope Christina finds her own wedded bliss with Josh.
