They became friends when they filmed the movie "Valentine's Day" together.
Roberts, who worked alongside the blonde beauty Swift on the 2010 comedy movie, has urged the 23-year-old singer to take up yoga to help her maintain her stunning figure and to keep her cool.
"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," contactmusic.com quoted a source as saying.
The 45-year-old Roberts, who has eight-year-old twins, Hazel and Finn, as well as five-year-old boy Henry with husband Danny Moder, has also been giving the "We Are Never Ever Getting Back Together" hitmaker some career guidance.
"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," the source added.
