Steven Tyler, Britney Spears and Tommy Lee are among the celebrities supporting legislation in Hawaii aimed at stopping paparazzi from taking photos at unwanted times.
The so-called Steven Tyler Act, named after the lead singer of Aerosmith, will be considered in the state Senate Judiciary Committee.
Stars who submitted written statements also include Avril Lavigne, Neil Diamond and the Osborne family.
The bill allows celebrities to collect damages from people who take photos or videos of public figures in an offensive way during their personal or family time.
The stars say the paparazzi have made simple activities like cooking with family and sunbathing elusive luxuries and the bill would give them peace of mind.
The National Press Photographers Association and the Motion Picture Association of America oppose the bill.
