AceShowbiz - Christina Haack or previously known as Christina Hall shares candid insights into the challenges she faced while filming the upcoming series "The Flip Off" with her now-estranged ex-husband, Josh Hall.

Haack told Entertainment Tonight that Hall's alleged insecurities and jealousy made it difficult on set. She claims that she deliberately dimmed her own abilities to avoid overshadowing him, leading her to question her own well-being.

"When someone is insecure by you and doesn't like to watch you win, that really puts a damper on everything," Haack said. "I feel like I was not shining as bright, to try to not make him feel emasculated. But who wants to live like that?"

The experience of filming with Hall was so unpleasant that Haack was grateful their split prompted him to leave early so the filming became "so much easier and so much better in every way."

One of the aspects that fuelled Hall's jealousy was Haack's amicable relationship with her ex-husband Tarek El Moussa who also stars on the show. Although some perceived their interaction as "flirty," she insisted it was nothing more "like a sibling type of thing."

After Josh Hall left the show, Christina Hall brought in another former husband, Ant Anstead, as a replacement. They have been spotted filming the show together.
