'I Am Solo' cast member apologized after revealing the behind-the-scenes of NCT member Doyoung's McDonald's commercial.

On March 16th, Go Cho Hee, who appeared on season 9 of 'I Am Solo', publicly apologized after revealing the behind-the-scenes of NCT member Doyoung's McDonald's commercial. Previously on March 15th, she went on Instagram live and during the live stream, she shared Doyoung's love for the hamburger on the set as she works for an advertising agency. 

She said, "Doyoung ate like 3 or 4 burgers in one sitting. He even shook his head when the manager told him to spit it out. It was so, so cute. I was like Doyoung is so adorable. Oh about the spitting out part, most celebrities spit it out. They either spit it out or pretend to take a bite. But Doyoung actually ate it all, smearing sauce on his face. From our perspective, who has to film, we love it. Because it looks real on camera." 

But on March 16th, she posted a public apology on her Instagram apologizing for speaking as if she saw every celebrity on set. She wrote, "Hello, this is Go Cho Hee. I apologize for conveying something as true when it was not verified to many of you during the live stream held on March 15th around midnight. During the livestream, I lost my cool and said something that I did not personally experience as true or as if I saw it, which is a big mistake." 

She continued, "All staff members and models do their best at the set for commercial. Despite this, my careless comment created a misunderstanding which tarnished their effort and passion. So I deeply apologize. I hope no one gets hurt because of something that is not true."
