What is Michael Pangilinan scandal?

Talented singer and actor Michael Pangilinan is in the news for all the wrong reason for a while now.
Michael rose to global fame after coming in second place in the second season of Your Face Sounds Familiar.
The 25-year old has amassed millions of fans across the world but some of them believe he was caught in some sort of “scandal”.
From what Twitter users have been writing, it appears that they have seen a purported video of Michael Pangilinan which they didn’t find appropriate.
But the claims he was caught up in a video scandal are unconfirmed and unverified.
