It's not every day that you get to see the HBO star misbehaving and her fans were definitely entertained by her cynical humor.

"Naughty and bad," she wrote in the pic's caption.

"We love a rebel!" a fan commented.

While the blue-eyed beauty may be an ice cream rebel on the streets, she's pretty disciplined regarding her craft. In her Women's Health cover story, Alexandra opened up about how she worked hard to improve her acting.

“I could memorize my lines, but finding my camera, finding my light, even learning how to walk naturally—it took a lot of practice. I knew something was wrong, but I knew I could fix it. I knew that I loved what I did and that I could be better.”

Her hard work definitely paid off, and she is now enjoying the fruits of her labor. Her performance as Rachel Patton in The White Lotus was recognized at the Emmy Awards, and she also has a couple of new big projects lined up. She has come a long way from being a teen star in the Percy Jackson series.

Aside from her brilliant performance, Alexandra's red carpet look also had people buzzing. The actress looked stunning in a sheer Dior couture gown that showcased her incredible figure and classic beauty.

Still reeling from the high of being at the Emmys, Alexandra shared a behind-the-scenes clip of her gorgeous red carpet look.

Alexandra looked back at the first time she stepped on the Emmys red carpet years ago and how it felt like to receive a nomination this year.

"I am nominated for an Emmy, which feels completely surreal," she said. "I think all the time about wearing a beautiful dress on the red carpet and I get to do it in real life. And that's really cool."
