Kid Cudi is leaving Lady Gaga's "Monster Ball" tour to focus on recording new material and "acting commitments," according to a statement released by his representatives on Wednesday (Dec. 16).

"Kid Cudi has decided to take an early leave of absence from Lady Gaga's Monster Ball tour, in order to balance his schedule surrounding the recording of his next album and acting commitments," reads the statement. "Cudi does not want to disappoint his fans and will move forward with his individual show dates in December and throughout the month of January."

The news follows an incident that took place at the "Monster Ball" tour's Dec. 12 stop in Vancouver, in which Cudi allegedly punched a fan. According to eyewitness accounts, the rapper mistook the fan, Michael Sharpe,  for a another concertgoer who had thrown a wallet onto the stage during his opening set. In a video that captured the incident, Cudi appears to jump offstage and throw a punch before being pulled away by security. Sharpe has since said he has no plans to press charges against Cudi.

At press time, a spokesperson for Lady Gaga said the singer has no comment yet about Cudi's exit, nor is there an update on who will replace him as her opening act. This is the second time Gaga will have to find a touring partner amidst controversy, however. Cudi was brought on to the "Monster Ball" tour after Gaga's "Fame Kills" tour, a co-headlining bill with Kanye West, was cancelled in the wake of West's VMA outburst against Taylor Swift.
