Nelly has apologised after posting a clip of a sex tape to social media.
The Hot in Herre singer - who last month told Madonna to 'cover up' in her sexy Instagram snaps - has claimed the now-deleted snippet was "never meant to go public".
The X-rated clip - which was screen-recorded by many fans before it was swiftly deleted - showed the rapper, 47, receiving oral sex from an unknown woman.
