Handlers for former American Idol Jordin Sparks are concerned about a “creepy” fan who has reportedly become obsessed with the “Battlefield” singer.

“I was in London when that happened to Leona Lewis. What’s wrong with people? I’e never been physically harmed but there is one guy we’re suspicious of. I think he has issues,” Jordin told Britain’s Metro this week. “He’s proposed marriage to me in letters several times and he’s sent me a cell phone to call him on. It was very creepy. My security people are keeping their eyes open.”
