According to 50, it’s Ja Rule’s fault.

A university in Long Island, NY was forced to cancel a concert headlined by R&B star Ashanti after only 30 tickets were sold to students. The concert was planned by Stony Brook University’s Student Activities Board.

Stony Brook University’s Student Activities Board issued refunds to the 30 ticket holders.

The School’s Undergraduate Student Government released a statement, “It is with deepest regret that we announce the cancellation of the Back to the Brook Vol. 1 concert scheduled for Thursday, October 25th at the Stellar Center,” read a statement.

The school graciously blamed inadequate marketing rather than lack of interest in Ashanti’s music.

Ashanti was actually a replacement for the original headliner, Teyana Taylor, who pulled out due to “unforeseen circumstances 2 weeks prior to the concert.”

Of course Murder Inc.’s arch-nemesis 50 Cent wasted no time letting loose on Ja Rule’s favorite collabo artist.
