Rod Stewart and Penny Lancaster rushed their two-year-old son to hospital after he developed a dangerous high fever. They drove to the hospital extremely frantic and Rod carried his son in his arms.

The tot was examined for an hour in West Palm Beach, Florida. He was diagnosed with a chest and ear infection and allowed home with anti-biotics on Sunday.

An onlooker said: “Rod looked very worried and Penny appeared tearful.”

Last night Penny said: “Alistair is responding well to the antibiotics at home.” He is Rod’s seventh child.
