Maddie & Tae Plot a Teary First Look -- With Each Other -- for Maddie Marlow's Wedding (Exclusive)

The girls caught up with ET Live on the 2019 ACM Awards red carpet, offering an update on the nuptials and their new EP.

Maddie Marlow better add tissues to her bridal checklist! 

The singer and one-half of country duo Maddie & Tae is set to tie the knot in November of 2019 with Taylor "Tae" Dye by her side as a bridesmaid. In an interview with ET Live at the Academy of Country Music Awards on Sunday, the girls decided that they may need a special first look moment together on the big day. 

"If she cries, I'm really gonna cry," Marlow confessed. "I asked [fiance] Jonah, I said, 'Babe, do you think you're gonna cry on our wedding day?' and he's like, 'Yeah! That's why we have to do a first look, because I need to get it out before.'"

"Oh my gosh, can we do a first look?!" Tae chimed in. "I'm going to be getting ready with you, but still, I'm gonna cry." 

Maddie gushed that Tae has been "the best bridesmaid a girl could ask for," but addressed one big snafu in the wedding plans: a date conflict on the Carrie Underwood tour! 

"We booked the wedding for September and then there's a tour date -- actually, the Nashville show, Sept. 27, was our wedding day," Maddie said. "We moved it to November. We're gonna get off tour and a couple weeks later I'm getting hitched! And my best friend's going to stand next to me!" 

The girls are set to open for Underwood on her Cry Pretty Tour, performing songs from their new EP, One Heart to Another, out April 26. 

"It's a long time coming," Tae said. "We're definitely really anxious to see how people react to the new music. All these songs, we've been living with for the past couple of years, so they're really special to us and we hope everyone loves them." 

But don't expect Maddie or Tae to get on the mic at the wedding. 

"I'm not making anyone sing at the wedding!" Maddie said. "No one's working. Even my band guys were like, 'Can we play?' I was like, 'Nope! You're not working. I just need your booties on the dance floor dancing. That's what I want you to do.'"
