Lady Gaga launches anti-bullying campaign
The singer has joined forces with Oprah Winfrey on Born This Way Foundation.
Lady Gaga has called on those with 'revolutionary potential' to help make the world a better place. The New Yorker was joined by her mother - the organisation's co-founder - and TV host Oprah Winfrey at Harvard University in America.
Joined by her mother and the foundation's co-founder Cynthia Germanotta and TV host Oprah Winfrey, Lady Gaga told more than 1,100 students to 'challenge meanness and cruelty'.
'I believe that if you have revolutionary potential,' said the superstar, 'you must make the world a better place and use it.'
Wearing a black statement outfit, Lady Gaga also said she wished there was a law for kindness and paid tribute to her mother.
'She is the sole reason that I am here today. She has always believed in me,' said the 25-year-old songstress. 'She has always been my support, and she makes me want to inject that sense of family and support into the world.'
The organisation, which takes its name from the singer's album and single of the same name, is designed to inspire and empower young people.
