*The latest sexually explicit song recorded by Brian McKnight for the online porn site YouPorn.com has been pulled from YouTube due to “inappropriate content.”

The R&B singer wrote the track as a thank you to the adult content portal for helping to sell the tongue-in-cheek song he released in April, titled, “If You’re Ready to Learn,” which offers sympathy to women left unsatisfied in the bedroom by selfish lovers.

McKnight’s latest ditty debuted on May 28 and was accompanied by a video featuring girls in bikinis, but the clip was deemed too explicit for YouTube and banned. YouPorn executives posted a different version of the video minus the scantily-clad women in a bid to get around the ban, but that promo was also removed from YouTube.

YouPorn rep Corey Price tells TMZ:

“I can’t believe with all of the crazy content that is posted to YouTube on a daily basis that this video of all things is being pulled repeatedly! Apparently you can show videos of bomb making and people killing kittens, but a bunch of hot girls dancing around in YouPorn.com bikinis is outlawed.”

McKnight continues to tell upset fans that his new racy tunes are not an indication of his new musical direction – it was all part of a prank.
