If you spent any time on Instagram on Friday, June 19, there’s a good chance you saw a lot of posts about Juneteenth, which marks African Americans’ emancipation from slavery in Texas in 1865 — two years after the Emancipation Proclamation was issued. The day is getting long-overdue attention and a push to make it a national holiday as part of the rapidly expanding movement in support of racial equity in the U.S.Lizzo participated in Juneteeth in true Lizzo form, with a video that’s not only informative and philanthropic but also undeniably eye-catching. In the clip, the Grammy winner sits on a staircase, surrounded by red candles. She’s nude, her body covered only by incredibly long, straight hair that reaches one of the lower steps. The look is reminiscent of the iconic cover of her album, Cuz I Love You.But her stunning hairstyle is far from the most important aspect of the video. “Happy Juneteenth, y’all,” Lizzo says. “This year, we’re doing Juneteenth in a major way. Not only are we celebrating a Black American holiday, but I’m holding a silent auction and a raffle so we can give back to Black organizations and businesses, specifically in the Twin Cities.”For a minimum $10 donation at lizzolovesyou.com, you could win a video call with Lizzo, a custom vase in the shape of Lizzo’s butt, two VIP tickets to an upcoming Lizzo concert (when coronavirus precautions allow), a Big Grrrl dance lesson with Lizzo, an all-access tour pass, and roundtrip airfare and hotel accommodations.Able to make a larger donation? You could also win a Lizzo autographed Quay sunglasses gift box, a Tracee Ellis Ross Pattern hair-care gift set, and Lizzo-branded “Buy Black” face masks.

One of the prizes is even a special-edition signed Cuz I Love You album cover so you can really relish Lizzo’s long-hair look.Ready to give back and get a chance to win?
