Tarek El Moussa admitted that he once accidentally called his new wife Heather by his ex Christina Haack’s name.

The real estate mogul, 43, made the confession on Tuesday in a fun behind-the-scenes video for his, Heather and Christina’s new HGTV show The Flip Off.

Tarek tied the knot with Heather in 2021 — three years after he divorced wife of nine years, Christina, in 2018.

In the Instagram clip, Tarek laughs as Heather playfully calls out their go-to contractor Bryan for calling her ‘Christina’ by mistake while they worked together on a home remodel.

‘Oh the bathrooms are free now!’ Heather quips as Tarek tries but fails to coax Bryan into admitting to the error on camera.  

Heather then exclaims: ‘[Bryan] called me Christina!’

Tarek, in an attempt to make Bryan feel better, tells him that he’s also called Heather by Christina’s name before — but insisted it only happened on ‘one’ occasion.

‘I did that one time. I’m lucky to be alive,’ he said, to which Bryan fired back: ‘I’m sure you’ve done it more than one time!’ 

‘No just once. It was more than enough,’ Tarek replied.

Heather then interjected to reveal that the name mixup had happened ‘at the beginning of [their] relationship,’ which would have been at some point in 2019.

The Selling Sunset alum then jokingly added: ‘And [Tarek] got cut. So, Bryan, get ready! What are we getting for free?’

‘Nothing,’ Bryan said. ‘You get my excellent work and attention.’

Tarek and Heather captioned the BTS clip, which was shared to Instagram and TikTok: ‘Anyone know of good contractors…we might need a new one after this… JK we love you Bryan #TheFlipOff’

Tarek’s confession comes shortly after Christina raised eyebrows by seemingly sharing closets with her ex’s new wife.

Last week, Heather loaned Christina a Sєxy red dress for date night with her new Christopher Larocca.

Christina wrote in an Instagram Stories post on Friday, ‘Thanks for lending me the gorgeous dress @theheartherraeelmoussa.’ 

Heather wore the busty, semi-sheer dress back in December and caught flack for wearing the Sєxy look as a mother, with one person writing online that it was ‘inappropriate.’

‘The dress is not not appropriate. You’re a mother now,’ one fan wrote on her Instagram post.

The former Selling Sunset personality responded, ‘So because I’m a mother I can’t wear a pretty dress that makes me feel beautiful?’

She added, ‘What does that have to do with anything? I am still a human and my name is Heather. I’m not just a mother. Choose joy.’

She doubled down on her stance as she took a screensH๏τ the exchange and posted in her Stories.

Heather, who shares two-year-old Tristan with husband Tarek, added, ‘Comments like this make me laugh.

‘I don’t even get offended anymore by the rudeness of others. I choose to spread joy, not hate.’

Christina, Heather, and Tarek now star on the new HGTV series The Flip Off — a spinoff of Flip or Flop, which Tarek and Christina made famous during their nine-year marriage.

Late last year Heather was criticized for wearing the dress, prompting her to clap back at the ‘rudeness’

Christina was married to Tarek from 2009 to 2018. They share daughter Taylor, 15, and son Brayden, nine.

She was married to Ant Anstead from 2018 to 2021, and the pair share son Hudson, five.

She is now in the wake of a contentious divorce from estranged husband Josh Hall, with whom she was originally intended to star on The Flip Off. 

Haack went Instagram official with her new boyfriend Christopher last week, as she sat on his lap in a pH๏τo from a private flight they took together.

The confirmation of their relationship comes after DailyMail.com revealed the two were dating in January.

‘Some plane flights must be hard posted,’ she joked in her caption.

Christina and the CEO of telecommunications service provider Network Connex were also pictured in a nighttime pH๏τo taken outside the jet after they touched down at an airport.
