Red Velvet's Yeri and Babylon will be working together for a new track!

The pic also displays the date of the release, which is on November 30 at 6 PM KST. In addition to the teaser, Babylon also uploaded a shot taken with Yeri at the backstage during Red Velvet's recently-completed concert "La Rouge" in Seoul, as well as the picture of Yeri with the congratulatory wreath he sent to her. The female idol liked his post and even left a smiley face emoticon in the comment section.

Earlier this month, Yeri got the fans anticipating a new release after she shared an interesting photo through her Instagram story. Along with the screenshots of her previous works as a solo artist and featured singer - Ragoon's "Story," "Hair in the Air" with NCT's Renjun, Jeno, and Jaemin, "Tuesday is Better Than Monday" with Giant Pink, and "Dear Diary" - a snap of an audio recording with the question "What comes next?" was in Yeri's Instagram story.

Since then, the fans wonder what Yeri has planned next. But after Babylon posted the teaser image recently, everyone now knows what the female artist will be doing.

This is the third time Yeri will be collaborating with an artist for a new song, following her releases with NCT's Jeno, Renjun, and Jaemin, and Giant Pink. Also, it will be her first time to be a featured artist after only six months since her collaborative song with labelmate Giant Pink, "Tuesday is Better Than Monday," which was issued in May of this year.

Meanwhile, this is Babylon's twelfth time to work with an idol for his new track. His first collaborated with rapper Dok2 in 2016 for the song "U & Me." In the following years, he works jointly with several artists, among them are Lil Boi, Kim Na Young, Chungha, Hwanhee, Vinxen, and Jung Ilhoon of BTOB. Then, last September of this year, Babylon released a collaborative song with Suzy, titled "Out of Breath."

Red Velvet's Yeri is known for her high notes and sweet voice, which make some people find her as a naturally good vocalist. Yeri is so good at singing that she became a trainee under SM Entertainment when she was just in her fifth grade of elementary school. And because of her excellent skills, Lee Soo Man, added her to Red Velvet in March 2015 even if the group had already made their debut in August 2014.

As for Babylon, he is not only famous as a singer. He is also a great rapper, dancer, and songwriter. He made his name known through posting mixtapes onto hip-hop websites that led to well-known rappers wanting to work with him, including Zico.

With two talented artists teaming up, fans expressed how excited they are for the upcoming single. Fans of Babylon and Yeri couldn't wait to hear how the song would sound. Some even commented that the collaboration of the two singers would be legendary.
