Gwyneth Paltrow has been voted most hated celebrity in Hollywood.

The 40-year-old actress surprisingly topped Star magazine's annual poll of the 20 most irritating personalities in film, music and television, with 'Twilight' star Kristen Stewart coming a close second.

Paltrow is thought to have amassed so many votes from American readers because of her reputation for leading a health-conscious lifestyle.

Meanwhile, moody-looking Stewart suffered due to the public exposure of her affair with married 'Snow White and the Huntsman' director Rupert Sanders last year behind boyfriend Robert Pattinson's back.

Latina superstar Jennifer Lopez placed third, with John Mayer - who recently split from Katy Perry and is famed for his womanizing ways - coming fourth, and romantic comedy queen Katherine Heigl ranking fifth.

The top 20 included some unsurprising entries, such as controversial teen idol Justin Bieber and reality TV star Kim Kardashian, but also featured some surprises.

Humanitarian activist Angelina Jolie was 15th on the list, with 'Two and a Half Men' joker Ashton Kutcher coming 13th.

However, R&B singer Chris Brown only placed 20th, despite receiving mass criticism this year for rekindling his relationship with Rihanna, who he was arrested for beating in 2009, and starting a violent club brawl with Drake.
