Trey Songz Says Fired Principal Knew Words to 'Best Friend'

Trey Songz is calling BS on the assistant principal who was fired for appearing in his music video, saying she knew every word on the track, "Best Friend."

Trey was leaving Henry's in WeHo Friday night, when he squarely took issue with Esther Adler-O'Keefe, who claims she had never heard the lyrics, which she says are "vulgar, offensive and demeaning."

Trey says he feels bad for her but she knew what she was getting into so it's on her for participating.
