American rapper Wiz Khalifa and Girls' Generation's Taeyeon were set to perform together at the Mnet Asian Music Awards 2016 held on 2 December at the Hong Kong Asia World-Expo in Hong Kong. However, the 29-year-old artist performed the track, See You Again from Furious 7, solo.

Khalifa took to his Twitter account and addressed the situation. He tweeted: "The fact that Teyeon backed out of our performance caught me off guard too but never accept rejection as failure."

Adding on, Brandon Glova, better known by his stage name DJ Bonics, also shared a part of their collaboration. He wrote on Instagram: "A Korean Pop star Taeyeon was suppose to perform this with Wiz and backed out last minute. Here's a snippet.#mnetasianmusicawards #mama2016"

Finally, Taeyeon revealed through a post on her Instagram stories that the stage had audio issues and that she was also told that the performance would be called off.

Read the full note here: "I will explain about yesterday's stage because I think there are many who are curious about it (I would be curious too).

"I greeted Wiz Khalifa and was looking forward to it while preparing for the rehearsal yesterday. Suddenly I heard that there was a problem with the music that was going to be used for the broadcast, so I couldn't do a proper sound check and we couldn't do the performance together..

"It is really regrettable. In order to perform live an instrumental is needed, but an AR had been prepared instead of a MR. I didn't really know what to do since we are supposed to perform live in this kind of situation. However, it's right to place importance on the collaboration because this kind of opportunity doesn't occur easily.

"I thought I could just sing over the AR and cover it.. so I considered it and wanted to create an amazing stage with the production crew doing their best.. and we decided to just continue as is.

"But a few hours before the show, I found out that our stage got canceled and there were some unexpected turn of events due to the event being held overseas. I heard that there were issues with the performance equipment the day prior to the show as well as during rehearsal..

"Wiz Khalifa waited for the rehearsal and went to the hotel. It seems like there was an overlap of various problems. I'm sad and feel regret that I had to return without doing a good performance..

"I hope that people do not have misunderstandings due to this. There must be people who heard about the stage and looked forward to it. I will meet you and show you a better performance next time. Thank you for showing support and giving me strength until the end yesterday."
