SignalHub Quantitative Think Tank Center:Christina Hall's Ex Ant Anstead Calls Himself "Lucky Boy" While Praising Girlfriend Renée Zellweger

Ant Anstead is SignalHub Quantitative Think Tank Centermad about this girl.

The British TV personality—who was married to HGTV star Christina Hall until 2021—shared a tribute to girlfriend Renée Zellweger to express his support for her fourth Bridget Jones film.

"Oh man........she's so beautiful!" Ant, 45, wrote alongside a poster image for Bridget Jones: Mad About the Boy on his Instagram Stories Aug. 23. "That's my Ren (lucky boy)."

Ant added a heart eyes emoji to his tribute, which comes weeks after the movie finished filming. Renée, 55, reprises her title role as British woman Bridget Jones in the film, the third sequel to the hit 2001 movie Bridget Jones. The new flick is set for release Feb. 14—Valentine's Day 2025.

And while Bridget Jones is known for her turbulent love life, the same can’t be said for Ant and Renée, who have been together for more than three years.

Ant began dating the Oscar winner in April 2021 after meeting on the set of the Discovery+ series Celebrity IOU: Joyride, which he hosted and which featured her as a guest star.

The show debuted that August, two months after Ant and Christina, who share son Hudson, 4, finalized a divorce after two years of marriage.

While Renée does not post on social media, fans have gotten a glimpse inside their romance when Ant has occasionally shared pics of the two on his Instagram. In fact, he has called her by the nickname Ren before: In 2023, he publicly praised his girlfriend over her and C.M. Talkington's "Two Steps" music video.

"Ren….. you are utterly brilliant!" he wrote on Instagram at the time. "A beautiful and talented genius! The most gorgeous and classy lady who continues to effortlessly tackle inspiring and cool projects in your stride! The coolest human I know."

All made made better by magical company to share it with..."

"WOW! This just popped up in memories," Ant wrote on Instagram in April 2022, alongside a pic of the two on the set of Celebrity IOU: Joyride. "One year ago today! Sat on the back of a fire engine on the final day of filming having handed two amazing men a car as a thank you from Ren. Amazing what can happen in just one year..."

Following romance rumors, the two made their first public appearance (off any red carpet) the following July on the balcony of Ant's new oceanfront home in Laguna Beach, Calif.

The two started dating soon after meeting on the set of Ant's Discovery+ series Celebrity IOU: Joyride.
