Selena Gomez is hosting a benefit to raise funds for her beauty brand's charity initiative.
The inaugural Rare Impact Fund Benefit is scheduled for 4 October in Nya Studios in Hollywood, California.
The evening is to support the charity's mission to reduce the stigma associated with mental health and expand access to mental health services for young people around the world.
"There is nothing more important to me than getting young people access to the resources that they need to support their mental health," said Gomez, founder of Rare Beauty and the Rare Impact Fund.
"This is a personal mission and the reason that I created the Rare Impact Fund."
Celebrities, philanthropists, mental health advocates as well as partners, supporters, and grantees of the Rare Impact Fund are said to be among the 350-strong guest list.
Gomez's Only Murders in the Building co-star Martin Short has been confirmed as the evening's entertainment, along with Grammy-nominated music producer Marshmello.
More details on the line-up will be announced at a later date.
"This event will highlight the importance of supporting youth mental health and raise funds for the incredible organisations providing critical mental health tools and resources for young people around the world," added Elyse Cohen, VP of Social Impact & Inclusion at Rare Beauty, and President of the Rare Impact Fund.
"With the support of our partners, donors, and community, we hope to further our mission to reduce the stigma associated with mental health and increase access to mental health services and education."
The Rare Impact Fund was launched with the goal to raise US$100m to address youth mental health.
Gomez's beauty brand donates 1% of sales to the fund.
Related organisations across North America, UK, mainland Europe, India and Brazil are said to have benefited from the project, along with more than 740,000 young people.
