On Friday's Daily Pop, Stewart, 31, opened up about the last-minute ceremony.

"It was really quick," she said of the planning process, adding that they didn't tell any of their friends beforehand. "Because the last time I told people about when I wanted to surprise you about the baby, everybody knew everything before I even got the chance," she said. "So I just wanted this to be a real surprise for the first time."

Finding her dream dress was equally spontaneous.

"When you type in 'white dress' on any sort of fashion website, it's like a bunch of summer dresses," she said. "And I was like, 'Oh great. Well, this is a mess.' And I literally saw this dress hanging on a rack and I'm like, 'This is a nightgown.' But then I put it on and I was like, 'This is the dress.' It was comfortable, it was so easy."

Stewart urged other engages couples to follow their low-key lead.

"If anybody at home is thinking about planning a massive wedding, or you're bummed out about what's been going on and you want to postpone, don't do it," she said. "It's the only way to get married, is the way we did it. It is so lovely. And the people that really matter are there. It is so intimate. You actually get to take in the day. There is no other way to do it. No other way."

Stewart announced the news of their engagement in July when she posted a photo of herself in a bathing suit showing off her diamond ring.

The couple then revealed they were expecting a baby girl just weeks later when they popped a balloon with pink confetti on Instagram.

"Been working on my dad jokes for years," McGraw, the son of Phil McGraw, captioned the video.

In March, Stewart — who filed for divorce from ex Brendan Fitzpatrick last year — confirmed she had been dating the "FLEXIBLE" singer for three months.

"Hot couple? Thank you!" she read aloud during her show.

While their relationship was still in the early stages at the time, Stewart revealed that she actually briefly dated McGraw when she was younger.

"We dated 10 years ago for a year and then he broke up because he was like, 'I'm not down with you, bitch,'" she said. "And then I was like. 'Fine, whatever, I'm over you, I don't care.’ And then I went on obviously to have another relationship."
