Rod Stewart sued by son's personal trainer

A personal trainer is suing rocker Rod Stewart over allegations his son Sean failed to pay for workout sessions.

Fitness guru Randy Rene has filed a lawsuit in Los Angeles claiming he is owed USD 5,440 for training Sean between March and May last year, reported TMZ online.

Rene alleged that Sean advised him to seek payment for the sessions from his medical insurance as the workouts were scheduled to help alleviate injuries he suffered in a car accident.

It is not clear why Sean's rock star father is named in the suit.
