Lady GaGa thinks there is ''a price to stardom''.

The chart-topping icon - who stars as an unknown singer-songwriter in the Bradley Cooper-directed 'A Star Is Born' - has claimed that fame and success can damage and undermine personal relationships.

Gaga, 32 - who was previously engaged to actor Taylor Kinney - explained: ''Success tests relationships.

''It tests families. It tests your dynamic with your friends. There is a price to stardom.''

However, Gaga admitted that her heartbreak has also served as a source of inspiration.

She told Elle magazine: ''I can't make music or act without using and accessing the pain that I have in my heart. I mean, what better place to put it? Otherwise, it's of no good use.''

In fact, Gaga revealed she relied on a lot of her personal experiences for her performance in 'A Star Is Born'.

She said: ''For me, in music and in acting, I'm always pulling from my past experiences, family dynamics, relationships, pain, happiness, joy, the roller coaster ride of my life - how that has kind of created this beautiful disco ball that's somehow refracted and fractured.''

Meanwhile, Shangela - who stars alongside Gaga in the new movie - recently revealed that the duo shared make-up tips while they were shooting the film.

The American drag queen said: ''One thing that Gaga taught me was less about make-up and more about how to be just natural through the make-up - really allow your talent to shine through, no matter what you're doing.

''So, that's one thing I picked up from her.''

And Shangela, 36, was happy to return the favour for Gaga.

She shared: ''Now, from me to her, I'm like, 'Oh sister! Let's get a little extra highlight over here on the side' - because you know I like to pop that cheek out.''
