Lee Yoo Bi's agency explained the truth behind the rumors that her 'Let It Go' performance was lip sync.

Today on SBS "Inkigayo", actress Lee Yoo Bi sang "Let It Go," the soundtrack of the animation movie "Frozen," as an initiation of becoming the new MC of the show.

But many internet users pointed out that her lips were not matching the singing, accusing her of doing a lip sync.

But Lee Yoo Bi's agency said, "Because she is not a professional singer, we were trying to prevent Lee Yoo Bi from making mistakes by playing the AR (where the MR and the singer's voice comes out together). Many were probably mistaken because they overlapped."

Internet users who saw this commented, "It was still good," "It's fine for her to do a lip sync, she's an actress," etc.
