Her empowering, oft-funny 4-minute speech also included a declaration and a mantra, "I am not a feminist, but I do believe in the strength of women. I don't really like to call myself a role model for my fans. I hope that I am an inspiration for them, especially young women. My mantra, especially for the ['Part Of Me'] film, was: If you believe in yourself, you can be anything."
Shoutouts to her mom, sister ("for keeping my head above water throughout… some of the hardest times of my life") and cousin ("who just had a baby with no epidural") followed.

"People don't want to look up to someone. They want to look at across at someone and say, 'That's my girl. She's singing something I don't know how to put into words. She's captured something and became the soundtrack of my life.' And I know that if I get out of line, my sister back home will whack me across the face - and so will my management."
