The Rare Beauty founder took time to reflect with an impassioned Instagram post on her 31st birthday, shining a light on the company's Rare Impact Fund, which was founded by Gomez and aims to raise $100 million over the next 10 years "to expand access to mental health services and education for young people around the world," according to the website.

"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," Gomez wrote in the caption.

She then called this her "true passion in life" before diving into her birthday wishes:

"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."
