There will be no flawless harmonies, mind-blowing beat boxing or Disney duets going down at Kirstin Maldonado’s wedding.

The 24-year-old Pentatonix singer, who announced her engagement to fiancé Jeremy Michael Lewis in May, says the two won’t be serenading each other at the alter on their big day.

“Everyone keeps asking us if we’re going to sing, but I feel like I would just want to relax. That would stress me out,” Maldonado tells PEOPLE.

The couple met through the NBC vocal competition show The Sing-Off in 2013 and even teamed up with Voctave for a Disney Love Medley duet in February, but they want to make sure their wedding day is solely about their love.

Maldonado doesn’t want her fellow bandmates to feel the pressure of performing on her special day either.

“If any friends want to do it, that would be really special. I would really appreciate that,” she says. “But we just want everyone to be able to relax and have fun and enjoy themselves and not stress out.”

However, it looks like Pentatonix won’t take up the bride-to-be’s offer. “We work like 364 days out of the year, so the one day we have off for her wedding, we probably won’t be singing,” band member Scott Hoying, 24, tells PEOPLE. “I’ll be taking Tequila shots.”

Fresh off the European leg of their world tour and gearing up for more U.S. dates in October, the multi-platinum acapella group says it’s essential to rest their voices when they can. They credit cough drops and water for keeping their voices pitch perfect while working all year. They’ve even partnered up with Ricola who will sponsor the rest of their tour and provide them with unlimited herb drops.

The “Can’t Sleep Love” singers also announced Thursday that they’re working on a new Christmas album, to be released in October, and are currently arranging new covers for their tour.

As for a wedding date and plans, Maldonado wants to take her time and enjoy being engaged to Lewis.

“I have a general idea of what I want to happen, but I haven’t really gotten in with people to start the process,” she tells PEOPLE. “I don’t really know yet, but I’m excited.”
