Tarek El Moussa offered a civil congratulations to ex-wife Christina Haack upon learning of her engagement to Joshua Hall on Monday.

The Flip Or Flop star, 40, seem surprised by Haack's news, telling People magazine: 'We ​​just heard [about the engagement,] but congratulations!' 

His fiancée Heather Rae Young of Selling Sunset added: 'Wow, awesome! We just want nothing but happiness for [Christina and Josh] and nothing but happiness for the kids.'

'We're looking forward to the next chapter of everyone's lives,' the realtor, 34, went on.

Tarek and Haack share two children and continue to work on their HGTV show Flip Or Flip together.

But according to insiders, things have been less-than-friendly between the exes.

Back in July it was reported that Tarek went on a vicious on-set tirade, allegedly calling the mother of his children a 'washed up loser.' 

Last week, Tarek broke his silence on the nasty verbal tirade, telling E!'s Daily Pop, he had a 'disagreement' with his ex,

Though he did not get into details about the altercation, he did admit there were 'choice words said on both sides.' 

'You know Christina and I, we worked together wow for over 10 years now and we've been working together as exes for five years now,' Tarek began. 'As you can imagine, it can be stressful working with an ex and we did have an incident where some choice words were said on both sides and I'm sure we both wish the whole thing never happened.

'I mean, I certainly do, but I mean honestly since we got into that little disagreement a few months back, I've just decided that moving forward, never again. 

'I never want to go through that ever again, I never want her to go through that again, and I know one day our kids are going to be older and I want them to know that we still care about each other and we still support each other, and it's really important to me.'

'The whole thing just sucked for everyone involved.'

On Monday, Haack subtly announced she was set to walk down the aisle for a third time, posting an Instagram with Hall. 

Not only was she wearing an engagement ring on her right hand but she also added lock and key emojis in her caption, seeming to allude to her being 'locked down' for marriage.

All but confirming the news, she changed her Instagram bio to read: 'Mommy. [engagement ring emoji] Josh Hall.'

It emerged back in July 2021 that Christina and Joshua had been 'dating for a few months', per Us Weekly. 

She went Instagram official with her new beau during their getaway to Tulum, posting a photo from their 'most whimsical/romantic dinner' date.

In the caption of a photo capturing a romantic moment from their getaway, she opened up about their unbelievable connection.

The reality star wrote about her non-traditional approach to self-healing, telling fans: 'I met Josh when I wasn't in a state of fear or fight-or-flight.'

Her journey included taking 'time off social,' and hiring a 'spiritual coach,' as well as smoking a psychedelic substance drawn from 'Bufo toad,' which she said 'basically reset my brain and kicked out years of anxiety in 15 mins.' 

'When we met this past spring, the synchronicities hit us so hard and fast they were impossible to ignore,' she recalled. 

It was uncovered by numerous outlets at the time that the hunk was a former police officer and now works in real estate, which Christina is plenty familiar with.

He is currently based in Austin, Texas and works for a successful realty firm in the area.

In September 2020, Christina filed for divorce from Wheelers Dealers star Ant Anstead citing irreconcilable differences, with their divorce finalized this past June. They share one-year-old son Hudson together.

Ant has seen moved on to romance actress Renee Zellweger, who he met while filming his show Celebrity IOU: Joyride.
