Harry Styles celebrated his 21st the right way - in Las Vegas.

According to the Daily Mail, Styles is set to spend his 21st in Las Vegas, and he’s been on a stateside victory lap in preparation. On Friday, he allegedly treated himself to a private retail experience at Beverly Hills’ Paige Premium Denim store.

But the actual date – Sunday, 1 February, went under an overall more charitable banner, as a group of 1D fans on Twitter raised over $16,000 for charity in Harry’s honour. The campaign and account (@1DFansGive) were created by superfan Amy Flanagan, MTV News reports, and the money raised will go to the London Lesbian and Gay Switchboard.

The drive is still ongoing. The London Lesbian and Gay Switchboard is a volunteer organization that aims to “provide an information, support and referral service for lesbians, gay men, bisexual and trans people and anyone who needs to consider issues around their sexuality.” Harry has publicly supported the organization in the past.

In addition, he has been an outspoken advocate for issues like LGBT rights and marriage equality. He has tweeted his support on several occasions and in August 2014, he made a huge statement of support by wearing gay NFL player Michael Sam’s jersey onstage.
