Julia Roberts has been sharing beauty tips with Taylor Swift.

The 45-year-old actress - who worked alongside the blonde beauty on 2010 comedy movie 'Valentine's Day' - has urged the 23-year-old singer to take up yoga to help her maintain her stunning figure and keep a calm mentality.

A source said: ''Julia's sharing her beauty tips, urging Taylor to take good care of her skin and to try yoga to tone her body, calm her mind and help manage stress.''

Julia - who has eight-year-old twins, Hazel and Finn, as well as five-year-old Henry with husband Danny Moder - has also been giving the 'We Are Never Ever Getting Back Together' hitmaker some advice to help her career.

The source added to National Enquirer magazine: ''Julia's urging Taylor to stay hungry and competitive but not let petty fights spill over into public.

''It's a case of Julia just trying to impart her hard-won wisdom to a kindred soul, and it's blossoming into a beautiful friendship.''
