ET can now confirm that Gwen Stefani and Blake Shelton will soon be newlyweds as the couple applied for their marriage license in Johnston, Oklahoma.

Although it's not so easy to get married in Oklahoma as it is in other states! You need to make sure you're legally licensed to wed first and once you've acquired the license, you've got just ten days to head to the altar before it expires. This hopefully won't be an issue for Stefani and Shelton!

The power couple had been dating for 5 years before Shelton popped the question in October 2020. It's all too cute, we know...

In an Instagram post last year, the "Austin" singer posted the cutest photo alongside a caption that melted hearts:

"Hey, @gwenstefani thanks for saving my 2020... And the rest of my life... I love you. I heard a YES!"

Stefani admitted back in April that she and Shelton are planning to keep their nuptials low-key and intimate, just like her recent bridal shower with her family.

"We're keeping it very simple. Really simple," she said during her appearance on Late Night With Seth Meyers. "I think the guest list will not have a lot of musicians. It'll be like my mom and my dad. It's literally going to be just family. We are looking forward to that, though."

"It's going to be fun. We're going to make it really fun, but it's not going to be a big event," she continued. "It's not like the queen and king are getting married or something like that."

But just wait...it gets EVEN cuter!

Stefani has also revealed the first song that she and Shelton are going to dance to as husband and wife.

"It's 'If You Leave' from the Pretty In Pink soundtrack," Shelton shared on The Tonight Show Starring Jimmy Fallon. "We talked about this. We both love the song. We're both fans of the '80s, why not? Don't you think that would be a great one, though? We've literally talked about that."

The songs first verse goes like this:

If you leave, don't leave now
Please don't take my heart away
Promise me, just one more night
Then we'll go our separate ways
We've always had time on our side
Now it's fading fast
Every second, every moment
We've got to, we've gotta make it last

It's not the usual pick for a couple's first dance, commemorating binding one another together but they're definitely the cutest!

And, how exciting that it will be happening pretty SOON too!!

We can't wait, can you?
