JLS star Aston Merrygold is said to be terrified by a break-in at his home. A fan was able to get into his bedroom.
Aston, 22, had just left his London home when the woman, who had been watching him, got into his room.
His frightened flatmate found the intruder who had climbed up the balcony.
Shaken Aston, who was on his way to Manchester for rehearsals, was told of the security breech in a phone call.
A JLS crew member told the Mirror: “A woman had climbed up to the balcony to his bedroom and got in through a window.
"She was believed to have been watching Aston's movements and was tracking him that day outside his home. She waited for his car to take him to Manchester before she made her move.
"She was discovered in Aston's bedroom soon afterwards. His clothes were sprawled on the floor but nothing was taken.
"Aston was freaked out when he heard - he's in total shock. It makes him fear for his life and he shudders to think what might have happened if he'd been in at the time."
Security has been beefed up at Aston’s home and at the homes of his bandmates Marvin Humes, 25, Oritse Williams, 23, and JB Gill, 22.
