Christina Hall seen filming The Flip Off with ex Ant Anstead in LA after she joked he could replace Josh Hall

Christina Hall was pictured filming her upcoming show, The Flip Off, with her second ex-husband Ant Anstead on Thursday in Los Angeles .

The British automotive expert, 45 — with whom she shares 5-year-old son Hudson — was seen flashing a bright smile at Christina, 41, as they chatted together, in photos obtained by People .

Other images showed Ant — who's currently dating Renée Zellweger , 55 — arriving to set and then meeting with Christina and the rest of the crew members.

Although the former couple, who called it quits in 2020, had a messy divorce and custody battle over their son, any bad blood between them seems to have dissolved.

'Even when cameras weren't rolling, they seemed very chummy,' a source told E! News of their on set interactions. 'It appeared they had really good rapport with one another.'

Ant and the reality TV star were spotted on set of the HGTV series just four months after Christina split from her third husband, Josh Hall , 43, who was set to appear on the show alongside her.

Christina previously joked that Ant could replace Josh on the show, though she later seemed to backtrack on the statement.

She said that it would be 'genius' to replace Josh with her second ex-husband, but then clarified that she 'can't work with anymore exes' as she's already starring alongside ex Tarek El Moussa.

An insider also told E! News that Christina and Ant had several 'light-hearted' conversations together.

Christina looked business chic for the occasion, wearing a black blazer black jeans, and leather high-heel boots with gold heels.

Her long blonde tresses were styled in gentle waves and cascaded down her back. The star shielded her eyes with a pair of black sunglasses.

Meanwhile Ant kept comfortable in a dark t-shirt, black jeans and white sneakers.

Earlier in the day it was reported Ant would be appearing on the show.

'Ant is going to appear on the show, but he won't be Christina's partner,' a source told People .

The Flip Off will star Christina as well as her first husband Tarek and Tarek's current wife Heather Rae El Moussa.

Her estranged husband Josh was also supposed to be a part of the show, which was going to follow the two couples facing off in a house-flipping competition. However, Christina and Josh split in July.

It's unclear if Josh will still have a role in the series.

The series was first announced in May 2024 and is set to premiere in early 2025.

Christina and Anstead dated for a year prior to exchanging vows in December of 2018 at their home in Newport Beach, California in winter-themed nuptials.

The former couple welcomed their son on September 6, 2019.

In November 2020, Christina filed to end their short-lived marriage.

Their divorce was finalized in June 2021, around the same time he began seeing Zellweger.

In August she told Backgrid that Hudson 'deserves to have us get along', and the exes have since re-followed each other on Instagram.

Christina also shares daughter Taylor, 14, and son Brayden, 9, with Tarek. Meanwhile Ant has two older children from his first marriage: Amelie, 21, and Archie, 17.

Christina's divorce from Josh is still ongoing.

Josh filed for divorce on July 15, after nearly three years of marriage, citing 'irreconcilable differences' and requesting spousal support from Christina.

Recently they have been battling over Christina bid to sell their former Tennessee marital home for $4.5million, with Josh filing a temporary emergency order to stop the sale.

Their split has been very contentious and public with Christina often calling him out on social media.
