While news of the couple's pairing came a few weeks ago, this is the first time they have acknowledged each other on the social media app.

Anstead shared a photo of him and Zellweger with his cohost Cristy Lee, promoting the premiere of their show "Celebrity IOU Joyride", which Reńne stars in and which is where their love apparently blossomed.

Anstead Posted His First Photo Of Him And Girlfriend Zellweger

Ant, who recently divorced from HGTV star Christina Haack, shared the snap earlier this week, urging fans to watch the first episode of his new show.

He hosts alongside Cristy Lee, and Renée was reportedly brought in to help with an episode.

The premise of the show is famous people gifting their loved ones with their dream cars. For the first episode, they are giving a vehicle to someone that Zellweger knows.

42-year-old Anstead and the 52-year-old actress, who used to date Jim Carrey, met in June during its filming, and sparks flew.

"Join @cristylee09 Ren and me as we pay it forward to two amazing men that gave so much to one of Ren’s dearest and closest friends," Anstead wrote in the caption.

He also called Zellweger "incredibly magical" in the post.

Fans Were Quick To Comment And Show Support

Although the post was not romantic in nature, most of the comments were filled with fans talking about the newly formed couple and wishing them well.

Many people were praising Renée and congratulating Ant on finding such a wonderful woman.
