Renée Zellweger helped plan Ant Anstead’s son’s birthday party

Renée Zellweger played a big part in her boyfriend Ant Anstead’s son Hudson’s 3rd birthday party.

When an Instagram user asked Anstead, 43, where Zellweger, 53, was when he posted party photos on Saturday, the former “Wheeler Dealers” host clarified that his girlfriend was not only in attendance but “helped plan the whole” event.

“Two lucky boys!” he added.

Anstead went on to tell his followers that his youngest child had “the best time” at the bash and “laughed so hard.”

“I’m going to be finding confetti and glitter for the next few months,” he wrote. “Totally worth it! … I love how kids just rip up the plans and get creative finding new ways to have fun!

“This party ended with the (drinks) ice buckets being used for dunking! Water balloons and a full on water fight!”

Tarek El Moussa, who was previously married to Hudson’s mother, Christina Haack, commented on the social media upload, “Big boy!!”

Haack, 39, shares daughter Taylor, 11, and son Brayden, 7, with El Moussa, 41, and she welcomed Hudson with Anstead one year before their September 2020 split.

The “Christina on the Coast” star celebrated their son’s birthday with an Instagram slideshow of her own.

“Happy Big 3️⃣ Hudson!! SO smart, cute and sweet,” she gushed. “We’ve been celebrating all week but can’t wait to make him feel extra special today. 🎂🎉💕.”

While Haack and Anstead have joint custody of Hudson, the “For the Love of Cars” presenter filed for — and was denied — full custody in April.

Anstead criticized his ex-wife’s parenting at the time, saying in court documents obtained by Page Six that Haack only spent “9 full days each month” with their son.

Not only did the “Flip or Flop” alum hit back by calling herself a “good mom,” but her third husband, Joshua Hall, came to her defense as well.

“Christina is a very driven and incredible woman who has an ability to brush anything off and keep herself composed while being a positive influence in these kids’ lives while achieving success in anything she does,” the realtor, 41, wrote via Instagram.

Anstead began dating Zellweger in the spring of 2021, shortly before finalizing his divorce from Haack.
