Zooey Deschanel and Jonathan Scott are making "slow" progress with their wedding plans

Asked how their wedding plans are developing, Zooey told 'Entertainment Tonight': "Well ... it's slow. But it's going."

The loved-up couple - who have been together since 2019 - insisted that they're not being deliberately coy about their plans.

Instead, Zooey and Jonathan are simply unsure of various details, including the venue and the date of their wedding.

The actress - who is best known for playing Jess Day on the hit sitcom 'New Girl' - added: "It all just has to be right."

Zooey previously claimed that she and her fiance are "so compatible".

The brunette beauty told PEOPLE: "Our personalities are so compatible. It's just that we're from different worlds. We identify as nerds, we'll have you know."

Despite this, Zooey feared that Jonathan was ghosting her at one point in time.

Jonathan explained: "We talked or texted every single day, I think, and still have every day since we've met, except for the [time] I went up on a packed trip up into the middle of the Rocky Mountains, where there was no cell service.

"She thought I was just blowing her off because I didn't respond for, what, three days or something."

Zooey and Jonathan celebrated their first anniversary amid the COVID-19 pandemic.

The actress took to social media in 2020 to hail the TV star, describing Jonathan as the most "kind, caring, hilarious, generous, creative, nerdy, handsome and all around incredible human".

She said on Instagram at the time: "I am so grateful for every smile, kiss, hug, snuggle, laugh, scrabble game, escape room, breakfast, lunch and dinner we share together.

"Even during the weirdest year for humanity I want a million billion more with you."
