A YG Entertainment official has told KpopHerald that they cannot confirm the news, but the BLACKPINK members still have time left on their contracts.
I’m not in the position to confirm the news, but our contracts with the members have not yet ended. It’s hard to confirm whether they will sign with The Black Label or not after their contracts end.
