Poor girl! One of Justin Bieber and Ellen DeGeneres’ biggest fans got the call of a lifetime on Monday, Feb. 16 — she just didn’t know it at first.

The “Boyfriend” singer, who vowed to appear on the talk show whenever he’s in town and has now appeared on the show three times this month, prank called a fan after telling the talk show host he’s a master at the game.

“I just love doing prank phone calls with my friends. Like probably top five favorite things to do,” Bieber, 20, explained, before phoning the fan with an epic British accent.

“She goes to UMass…she’s a really good student so I think we should scare her and say we got her grades and she’s not doing too well,” he told DeGeneres before making the call, during which he pretends to be Peter, the head of University of Massachusetts Amherst’s English department.
