CAMBRIDGE, Mass. - Lady Gaga has launched a youth foundation by urging young people to "challenge meanness and cruelty."
The singer spoke Wednesday to a crowd of more than 1,100 students, faculty and invited guests at Harvard University.
Oprah Winfrey, U.S. Health and Human Service Secretary Kathleen Sebelius and others joined her in kicking off the Born This Way Foundation. It's named after her 2011 hit song with lyrics that promote self empowerment.
The singer says the foundation's goal is to empower youth and inspire bravery.
She urges students to do "simple acts of kindness" in their communities to help foster acceptance, tolerance and individuality.
Earlier Wednesday, Lady Gaga caused a sensation on the Ivy League campus when she arrived in Harvard Yard in a sleek black dress, tall hat and platform shoes.
