The singer urged her social media followers to lend their support to the Rare Impact Fund, which is seeking to raise $100 million over the next decade to expand access to mental health services and education for young people around the world.

She wrote on Instagram: "I am thankful for so much in my life and one of the things I am most thankful for is the work we’ve been able to do with the Rare Impact Fund through @Rarebeauty. Because of YOU we’ve been able to raise awareness and increase access to mental health services for young people. This is my true passion in life.

"People keep asking me what I want for my birthday, and I tell everyone the same thing please do not get me anything but if you want to do something for my birthday, please donate to the Rare Impact Fund. If you have the means, consider donating to help us make a difference.

"I LOVE YOU ALL! (sic)"
