The singer, who won The X Factor last year, asked the talent show's executives to move her from the London apartment after the incident. She is now living where Lemar from Fame Academy resided previously, reports the News of the World.
A friend said: "It all happened when she got back from recording her album in LA. This gang wouldn't leave her alone and it took a real toll on her. One day Alex was driving her Mini Cooper convertible with the roof down to her flat when these lads just started throwing stones and hurling abuse at her and a friend.
"They were shouting, 'Oh, you think you're so f**king amazing because you went on the f**king X Factor'.
"One of the rocks hit her friend. Alex was horrified and realised she had to get out of there."
The source added: "She just wants to be safe, secure and left in peace. She's much happier now."
