Actress Jennifer Aniston says one of her biggest guilty pleasures is watching a TV show which explores what happens when people go under the knife to improve their appearance, and things go wrong.

"My guilty pleasure is the E! TV show 'Botched'. It's all about plastic surgery gone wrong. It should be renamed 'Crazy People'," Aniston said.

When she isn't working or watching TV, the `Friends` star finds meditation the perfect way to ease stress.

"I've been meditating for about four years. I take 20 minutes in the morning and the evening. It's hard to put your finger on what's changing but you do feel a release of stress," she said.

The 46-year-old actress has experimented with a number of hairstyles over the years but admits her favourite is a "boring" hairdo, reports femalefirst.co.uk.

"I've tried lots of hairstyles over the years - I had the 'Rachel' and I've gone from a super-long to a super-short bob. But I'm actually really boring and my favourite is the straight-down-the-middle seventies babysitter hair," she said.

"The worst thing I've done in the quest for beauty was to iron my hair to straighten it," she told Tatler magazine.
