G-Dragon made a formal apology at a Big Bang fan event in Japan on Saturday.

Big Bang hosted Big Bang Special Event 2017 at Kyocera Dome in Osaka, Japan.

Before kicking off the two-day event, G-Dragon apologized to the audience as the group’s leader.

“I’m very sorry to have caused you so much anxiety. We won’t let this happen again. Please continue to support us,” the artist said.

T.O.P followed that up Sunday with a written apology in a letter to fans for his marijuana use.

“I’d like to extend my sincere apology to many of you for causing such huge disappointment and disturbance. I feel so embarrassed to even show myself in front of you to apologize,” the letter said.

On Thursday, T.O.P came under fire following the revelation he had tested positive for marijuana use. He admitted to having smoked marijuana several times in October 2016.
