Chloe x Halle are gearing up to release a new song on Friday and, leading up to its release, they’ve issued a challenge to fellow performers.

On Instagram on Tuesday, the crooning Atlanta sisters shared a TikTok video of them singing their single “Do It.” Harmonizing and snapping their fingers, Chloe and Halle Bailey had a call-and-response moment toward the end of the brief clip.

After encouraging fans to presave the tune via an in-bio link, the duo then called on "all our singers out there" to"try this singing challenge with a friend."

Singers responded, and the duo sahred some of the submissions in their Instagram Story that day.

Meanwhile, nonsingers remained in awe of the R&B duo’s talent.

“Imagine having amazing voices like these?!” a fan said on Instagram.

Another commented, “Y’all sound amazingly beautiful.”

Twitter users also praised the Bailey sisters’ vocals.

The siblings are also fresh off their appearance on ABC's "The Disney Family Singalong: Volume II," on which the 21- and 20-year-old belted out "Almost There."

Joined Sunday night by Broadway star Anika Noni Rose, who played Princess Tiana in the film, the singers performed the tune from the 2009 film “The Princess and the Frog.”

It’s especially good for Halle Bailey, as she has been cast as Ariel in a live-action adaptation of “The Little Mermaid.” When the news broke last year, it sparked backlash online. But Halle Bailey told Variety in August that she wasn’t focused on the negativity.

“I feel like I'm dreaming and I'm just grateful and I don't pay attention to the negativity,” she said. “I just feel like this role was something bigger than me and greater and it's going to be beautiful. I'm just so excited to be a part of it.”
