If you've heard any news lately. You'd know that rumors are going around about Minzy leaving 2ne1 and that 2ne1 are gonna disband soon.
Sadly regarding Minzy, YG made a statement as of April 5 saying that Minzy has chosen to not renew her contract with YG.
We'll miss you Minzy!
However the rest of the members have chosen to renew their contract. During the statement YG made, they said that we should expect a comeback some time in the summer. Hopefully this means that CL will soon fully debut into America.
