Addison Rae Sizzles In A Sparkly Cut-Out Dress With High Slit At AmfAR Gala

Addison Rae looked stunning as ever!

The TikTok star, 21, was among the celebrities who turned out to support the amfAR gala in Los Angeles on Thursday night. According to the gala's official website, the annual black-tie event has raised over $15 million for its life-saving research programs.

Some of Hollywood's biggest stars were in attendance, including Diane Sawyer, Goldie Hawn, Heidi Klum, Tom Hanks, Kate Hudson, Lady Gaga, Christina Aguilera, Sean Penn, Lea Michele, Matt Bomer, Zendaya, Angela Bassett, Rihanna, Justin Timberlake, Jamie Lee Curtis, Diane Kruger, Sarah Paulson, Emma Roberts, Sarah Hyland, Sophia Bush, Miley Cyrus, Gwyneth Paltrow, Sharon Stone, and more.

The ensemble was made of two different types of fabrics. The upper part was sparkly with a scooped neckline that sat low on her chest -- allowing her to showcase her cleavage. The garment was sleeveless, but the material stretched over her chest and wrapped around her neck. It also featured a cut-out along the midriff, showing a glimpse of her taut tummy.

The lower portion looked similar to that of a wrap skirt. It was black and crafted in satin fabric. Its high slit displayed Addison's flawless leg.

Addison had her locks styled in a sleek bun with a center part. Her makeup application was glamorous, including heavy mascara, light pink eyeshadow, a hint of blush, and pink lipstick. The "He's All That" star wore a couple of accessories, such as a pair of statement earrings, a bracelet, and a ring. To complete her look, she wore black open-toe pumps.

Addison could be seen striking several poses on the carpet. Meanwhile, she also uploaded some BTS snaps to her Instagram account. She was snapped on the balcony, looking so gorgeous in her dress. The close-up shots gave fans a better look at her makeup.

The steamy upload didn't fail to capture fans' attention, reeling in more than 690,000 likes and an upward of 1,600 comments in the first three hours of posting.

"I've been waiting all day for your post," one follower commented on her post.

"THE PRETTIEST GIRL I’VE EVER SEEN," gushed another user.

"You’re actually perfect," wrote a third Instagrammer, adding a string of red heart emojis.

"Addison is the prettiest and we all know that. Drop-dead gorgeous!!!" read the fourth comment.

Addison has been attending star-studded events lately. Last month, she went to Elle’s 27th Annual Women in Hollywood Celebration at the Academy Museum of Motion Pictures in Hollywood, as per a report by The Blast.

Addison also rocked another cut-out piece during the event with a thigh-high slit. It was all-black with a one-shoulder design. At the time, the internet sensation also had her hair styled the same way -- pulled up in a bun to show off her lovely facial features.

In August, Addison also attended the annual Met Gala in New York. Although she got a lot of backlash for being invited, she still rocked the night by wearing a stunning red gown as she showcased a shorter, lighter hairstyle.
