Gwen Stefani and Blake Shelton enjoyed their first Thanksgiving dinner as an engaged couple days after the actual holiday.

Stefani, 51, shared on her Instagram Story a video from their belated Thanksgiving celebration on Sunday night. She explained in the clip that she and Shelton, 44, will be live on "The Voice" the following day.

"We are actually having Thanksgiving today, right now," Stefani said. "And then we’re going to be live on 'The Voice' tomorrow, which is crazy!"

Stefani then panned to her fiancé, who jokingly guzzled down a bottle of wine. "Oh my God!" the "Hollaback Girl" singer said with a laugh as he drank, "He's totally faking!"

Stefani also showed off their seasonal spread for the holiday which included corn, pumpkins, candles and flowers.

Despite celebrating the occasion a few days late, Shelton posted a sweet tribute for Stefani on Thanksgiving. "What a year we’ve all had, but there is still plenty to be thankful for! Happy Thanksgiving y’all!!!” he wrote on Instagram alongside a throwback photo of them.

"Love u @blakeshelton gx," commented Stefani on the post.

Shelton proposed to the No Doubt singer in October, five years after they started dating.

"Blake has been the one who wanted to take it slow in the beginning but recently he decided it was time. During the pandemic, they’ve had lots of downtime together and he truly saw the importance of spending life with the person you love," an unnamed source told Entertainment Tonight at the time.

"Gwen takes marriage very seriously and was disappointed that her first marriage [to Gavin Rossdale] didn’t work out," the insider continued. "She wasn't in a hurry because she wanted to ensure Blake was ready."

Her sons with ex Gavin Rossdale — Kingston James McGregor, 14, Zuma Nesta Rock, 12, and Apollo Bowie Flynn, 6 — were reportedly involved in the proposal, according to another insider.

"Blake is very close to Gwen's boys," the unnamed source told ET. "They talked it through and Blake made sure they were part of the excitement! Blake had a custom-made engagement ring. He knows the designer and has used them in the past to make bracelets for Gwen."

Stefani gave fans a glimpse at her diamond bling when she accompanied Shelton to the 2020 People's Choice Awards earlier this month. She opted to wait for Shelton in the car while he accepted his top country artist award.

To keep herself entertained, Stefani shared a series of videos on social media of her cheering her fiancé on. In one clip, she placed her hand on her face, revealing the giant diamond ring she received from Shelton when he proposed to her.
