Although it’s been nearly six months since Justin Bieber was falsely accused of impregnating a fan backstage at a concert, the pop superstar hasn’t quite forgotten the incident.

Bieber took to Twitter on Saturday to call out 20-year-old Mariah Yeater for claiming in October 2011 that he was the father of her child.

The tweet was sent during what Bieber calls “#RandomTwitterHour,” where he sends messages to his more than 20 million Twitter followers about anything he wants.

He tweeted a message that mentioned her by name and included a YouTube clip of Borat — a film and TV character played by actor Sacha Baron Cohen — repeating, “You will never get this. You will never get this. La la la la la.”MORE
