Christina Haack's Ex Husband Ant Anstead Follows Her Back on Instagram After Several Friendly Exchanges

After Christina Haack (formerly Hall) re-followed her ex-husband Ant Anstead on Instagram this summer, he appears to have reciprocated. 

The British automotive expert and TV host, 45, shared a photo of the former couple’s son, 5-year-old Hudson, with his youth soccer team on Saturday, Oct. 19, writing, “The ‘Golden Chameleons’ crushed it this morning."

Anstead tagged Haack, along with his other two children — Amelie, 21, and Archie, 18, whom he shares with his first wife Louise Storey — and Haack reshared the post to her own Instagram Stories.

While Haack and Anstead have previously had a contentious relationship due to a heated custody battle after their split, they’ve shared several friendly interactions on social media in the last few months, following her split from her third husband, Josh Hall, in July.

Last week, Haack liked a series of photos that Anstead shared of Hudson after the father-son duo spent a beach day together in Laguna Beach, Calif. 

In September, Haack tagged Anstead in a video of Hudson’s first soccer practice.

And when Anstead posted a birthday tribute for Hudson that same month that referenced his girlfriend Renée Zellweger, Christina commented on the post.

"Happy birthday Hudzo! WOW what a privilege it’s been to witness you become a bright, sparkly, funny, brilliant, generous magnetic, talented and kind little man," Anstead wrote on Instagram.

"You have taught me so much about so much! It’s been a privilege to do this dad thing all over again. You humble me and fill everyone around you with joy and love," he added. "NayNay and I love you very much! Happy 5th birthday Hudzo ❤️ x."

Haack's reply read, "Happy Birthday to our sweet boy!"

Christina also liked a birthday post Ant shared for Amelie, who is her former stepdaughter.

In late July, Christina told Backgrid that Hudson was an important reason for her decision to re-follow Anstead. 

“Ant and I share Hudson... and I feel like he deserves to have us get along,” she said.

Christina also responded to a fan’s suggestion that Anstead join The Flip Off, her upcoming HGTV series in which Josh was originally set to be her partner in a house flipping competition against her first husband, Tarek El Moussa, and Tarek's current wife, Heather El Moussa.

“How awesome would it be to have Ant replace Josh on The Flip Off? Ratings would go through the roof. If it happens, I need some credit. Lol,” the comment read.

Christina replied, “LOL that would be a genius 'ratings' idea just sayin.”

She later clarified her stance on whether Anstead might take Josh's place on the HGTV series.

“It would be good for ratings, but I can’t work with any more exes," she told Backgrid. "I already work with Tarek.”

Josh filed for divorce on July 15 after nearly three years of marriage, citing "irreconcilable differences" and asking for spousal support from the HGTV star.

Christina responded with her own legal filing on July 24, which asked that neither spouse be allowed to request support.

On Oct. 16, Josh made a rare public statement addressing a claim that he requested $65,000 in spousal support from Christina on his Instagram Stories.

The exes have been in a public dispute over finances and one of the homes they shared during their marriage.
