Lisa alter ego?

I saw on YouTube that Lisa is supposed to release an album next year and that she also said that here

Lisa apparently said that in Thai as a little spoiler for next year, and then I saw videos where there was a teaser for it and you could see Lisa walking around, then rockstar came on and she was playing a guitar and her face didn't look like it had been cut in and you could see this star on Lisa that said "Alter ego". Is it true that she's releasing an album next year?
