Janet Jackson is thought to be suffering from "exhaustion." The "Feedback" singer, who was rushed to hospital after being taken ill during a sound check for a concert in Canada, had previously refused to comment on the reason for her illness.

But a close friend of the star's boyfriend Jermaine Dupri claims Janet is just very "tired".

Justin Timberlake's manager has offered to manage Ali Lohan's singing career. Johnny Wright - who has managed bands including the Backstreet Boys, New Kids on the Block and singers Britney Spears and Janet Jackson - is keen to help Lindsay Lohan's 14-year-old sister get her professional life back on track.

A source said: "Johnny Wright, who manages the Jonas Brothers and Justin Timberlake, has offered to help out Ali and guide her career, but we'll see if Ali's mom Dina will be into it. She wants full control and the full manager's fee for herself."
