It seems like it's just another rumor after all. Earlier, Newsen reported a rumor stating that Jaebeom, ex-leader of 2PM, would be returning as the main character of a music video in the States. JYPE has already denied the legitimacy of this rumor. JYPE said to MoneyToday News on the 22nd:

Truthfully, we are very unaware of this. Jaebeom did not record a music video in America. We talked to our contacts in America and found out that this never happened. We don't understand why people who have no relation to Jaebeom keep making up rumors. We're very disappointed.

How many rumors have come up over the past two days? But I'm sure this isn't the end of them.
