Brian McKnight caused an uproar in April after he released an adult parody song that none of his fans can forget called “If You’re Ready To Learn,” but he may have just topped it with his latest vulgar song.

As a thank you of sorts to an adult website for helping boost sales of his adult tutorial song, Brian has penned them an anthem that’s even more x-rated than the first. With his recent dabble into the x-rated world, we want to know, what do you think of this new side of Brian McKnight?

If you thought his first adult song that was all about how to satisfy women was dirty, then his new vulgar song might shock you even more.

TMZ.com acquired a clip of the Brian’s new “anthem” for YouPorn that has Brian singing all about “anal.” The lyrics are even more shocking than his ‘adult tutorial’ and makes us wonder, what is Brian thinking?

You can listen to the song here (warning, VERY explicit language used, but is bleeped).
