Arian Berisha, 21, pleaded guilty earlier this year (15) to hurling a glass at the Sexy and I Know It hitmaker as he partied at The Golden Sheaf Hotel in Sydney in August last year (14), and the star later received treatment for a head wound.

Berisha's lawyer told a court in the city on Tuesday (26May15) that the incident was an ice bucket challenge-style "prank" and that his client had only meant to throw water over the star but the glass slipped from his hand.

However, a prosecution lawyer told the hearing, "(There was) no ice, no bucket, no challenge. If he wasn't a celebrity, he wouldn't have been targeted and we wouldn't be here today."

Berisha was sentenced to a two-year good behaviour bond.
