The 'Duck Dynasty' star tells ET exclusively how their relationship blossomed.

Sadie Robertson has a new beau!

The 20-year-old Duck Dynasty star and author of Live Fearless confirms to ET that she is dating actor Austin North. The exciting news comes a day after Robertson shared a cute photo on Instagram of herself and the 21-year-old All Night actor after grabbing ice cream together. So how did the two meet?

"Austin DMed me on Twitter two summers ago and quickly got out of the DMs by giving me his number," Robertson tells ET. "We spent most of that summer calling and texting until things fizzled out just from lack of never actually meeting. Almost two years have gone by and I was in LA for my book press, and my friend said she wanted to set me up with someone at Churchome when we went on a Wednesday night, and to my surprise it was Austin!"

"We both laughed and couldn’t believe the randomness of finally meeting [through] a friend who had no idea we even knew each other," the Dancing With the Stars alum says, adding that they "instantly had heart eyes for each other" and there was definitely an "instant spark."

"We hung out the next two days I was in town," she continues. "Then I came back and he took me on our first official date. It’s new, but we both are so happy and just having fun."

North is best known for his role as Logan Watson in the Disney Channel show I Didn't Do It. He also appeared in the Kickin' It, A.N.T. Farm and Jessie. The actor has already met Robertson's mom, Korie, and has her approval! "She was like, 'Wow, he’s so your type of person. He’s doesn’t take himself too seriously and laughs with you,'" she shares. "We’re becoming each other’s best friend. It’s kinda fun."

It's only been a month since the two became official, but she's enjoying picking up right where they left off and sharing this journey with all her fans.

"We both have enough confidence in [our relationship that] we want to share it with people," she says. "I have always said differently because it’s something I have been afraid of, to be publicly official. But with him, everything’s different."

"He’s so sweet. He’s so much fun. He loves the Lord and is passionate about life," Robertson gushes. "We laugh a lot and, just honestly, both really like each other and ice cream. We’re cheesy, but thriving."

Both Robertson and North are busy with their careers, but Robertson says they keep in contact by FaceTiming, which she stresses is "definitely key" in a long-distance relationship.

"We are both super supportive of each other’s career and that’s been so awesome," she explains. "We look forward to getting to support each other in different things. He already plans to come see me speak at an upcoming event, and I can’t wait to watch his new show coming out. The good thing is I have a lot of work in LA right now, so I will be out there often, and his sister is working in Nashville with her music. So we are just going to make it work."

Just last month, Robertson sat down with ET and opened up about her struggles with dating in the public eye.

"My dating life was very public and most everything in my life is very public, the flaws and all," Robertson shared at the time. "I love that because I can speak into those things in other people's lives and I always want to be real and vulnerable, but I do think there's a point in your love life or whatever that you have to establish it for yourself first and then build a firm foundation in it before you share it with the world."

"People's hearts are so valuable and it's so scary to think about somebody getting their heart broken," she continued. "That is genuinely scary. And so it's like, that hesitation to even jump in because once you've experienced heartbreak, you're like, 'Oh man, what if it doesn't go...' You start to overthink."
