Maddie & Tae have a whirlwind 2019 planned. They're offering direct support on Carrie Underwood's Cry Pretty 360 Tour, and Maddie Marlow will be tying the knot to longtime boyfriend Jonah Font.

In an interview with Taste of Country Nights' Sam Alex, the duo spill some of the wedding plans, like that Taylor Dye will be a bridesmaid.

"We're gonna do it in Nashville next November because we're going out on tour with Carrie which is so exciting!" Marlow exclaims. "A huge blessing with the tour and a huge blessing getting married. We moved our wedding date a couple times — one for the Carrie tour and one for the CMAs."

Marlow says it's easier to cut down the guest list by having their nuptials in Music City, as she and her fiancé have a lot of family in Texas. They're expecting about 150 people. Her bridal party will include seven bridesmaids, including Dye and the duo's merch girl, plus Marlow's younger sister, childhood best friend and Font's three sisters.

Dye already has a few ideas for Marlow's bachelorette party, but promises it won't be too extravagant or wild. "I do have some tricks up my sleeve. She wanted something chill. We're not gonna do pedal tavern, no way," she insists.

Marlow doesn't want flowers at her wedding because the thought of throwing them all away at the end of the day makes her sad. She's not sure who will officiate, either, although Dye has suggested her brother, Mason, whom she says will "officiate me."

Don't get excited — Dye isn't engaged yet — but Marlow hints that it won't be much longer before she is. "She's not far behind," her bandmate says. When Dye does get engaged, she wants to get married very soon after. A long engagement just isn't for her.

And, while Marlow is still fleshing out the details of her big day, there is one thing she's sure about:

"I don't want anyone playing at our wedding, so it doesn't feel music industry-ish," she says of the idea of a fellow country artist performing at their reception. "I'd be down for a mariachi band at the end of the night."

Maddie & Tae's new single, "Friends Don't," is out now. Their sophomore album is expected early next year.
