Lindsay Lohan is worried at her little sister's sexy new image and is determined to keep her on the straight and narrow, it has been claimed. Lindsay is reportedly terrified her teenage sister will follow in her destructive footsteps and has warned Ali: 'Don't end up like me.'

Ali, 13, appears completely dolled up in promotional shots for her mum Dina's new U.S reality TV show. "It was the final straw for Lindsay," an insider told Star magazine. "Lindsay knows that Ali idolizes her, but she also realizes that she was a bad influence on her for years. "

Lindsay's afraid that Ali will follow in more than just her footsteps onto the screen."

"She doesn't want her to ever experience addiction, rehab or jail, like she did. She's disturbed by how the makeup made Ali look 25. Lindsay wanted to know if their mum convinced her to take the sexy photos, but Ali told her that she loved the look. She asked Lindsay when she should get her own stylist and personal assistant. Lindsay doesn't fault Ali, since she's just following everyone's lead - the way Lindsay did - but she wants to fix this while there's still a chance."
