Singer Minzy gave some helpful tips to rookie trainee group MYTEEN, working their way to stardom on MBC Music's 'MY TEEN GO!' on January 31.

Minzy made a guest appearance on the show, surprising the members. She asked questions like, "How is it? Do you guys make a good team? Teamwork is important." Trainee Eunsoo replied, "We make a good team, we're planning to debut together."

The former 2NE1 member then recalled her days during "I Don't Care" promotions, saying, "Our boss turned up on the day prior the show and changed the entire dance choreography. We had to practice until 8am and had to go perform."  She added, "Once you start performing more often, you'll get used to it. The important thing is to practice until you memorize the dance moves. Give it your best."

With that, she directed the trainees to work on the middle section of their dance choreography, coaching them and giving advice along the way.
