Coming off of the disbandment rumors, 2NE1 fans are once again worried about the future of this group due to recent videos and developments.

On November 4, 2NE1 performed at the Alexander Wang X H&M launch party in Shanghai, China. After videos of their performance surfaced online, certain observers noticed something potentially off between CL and Dara.

"What's up with CL not dancing the choreography," commented xDaLu on YouTube. "And so distant with Dara. Hope they're okay."

"It seriously looks like Dara is avoiding CL," wrote Marlene Flores on November 6. "I'm not crazy because I saw it throughout the whole video, not just once or twice. Especially in the last part Dara's smile fell when CL passed by and then it came back."

"Oh no. I don't like this."

Fans are also concerned because various sources allege that CL is currently in the US for her solo debut. Because Dara's birthday is on November 12, it's possible CL will be missing the celebration.

On November 6, Dara uploaded a photo from the final stop on 2NE1's "All or Nothing" world tour on Instagram.

"CL left for the US and Dara uploaded this," commented BlackjacksOf21 on Twitter. "I know exactly how it feels."

Last month, 2NE1 experienced disbandment rumors after CL confirmed her American debut due to Minzy changing her Instagram and Twitter handle. However, YG Entertainment released statement on the matter shortly thereafter.

"It is the artist himself/herself who controls his/her own SNS activities," said YG Entertainment according to Koreaboo. "We want to tell you that we are very careful in telling you anything. We want to tell you that the timing of the announcement of CL's American debut and the timing of Minzy changing her Instagram ID coincided. There is no special meaning to what happened."
