Miley Cyrus celebrated the 13th anniversary of "7 Things" by having her fans track down her music video co-stars.

On Thursday (June 17), the "Prisoner" singer asked her fans to find the girls who were featured in the video, which came out in 2008. Years later, it turns out many of the "7 Things" girls also worked elsewhere in the entertainment industry — and some are even famous now.

One of the video stars, Maiara Walsh, appeared on Desperate Housewives and co-starred on Disney Channel's Cory in the House. Walsh is also a writer, singer and filmmaker.

Brooklyn Beckham's fiancée Nicola Peltz was also showcased in the music video. She was just 13 at the time. In 2016, she acted in Zayn Malik's "It's You" music video before starring in films such as Transformers: Age of Extinction and The Last Airbender.

Liana Liberato responded to Miley's request and thanked her for letting her 12-year-old self cry during the initial video shoot. You may recognize her from her roles on Light as a Feather, If I Stay, To The Bone, Trust or Stuck in Love. She also starred in the "Stranger Things" music video from Kygo and One Republic.

If you're wondering why Carissa Alvarado looks so familiar, it's probably from her time on America's Got Talent, where she appeared as a musical act during Season 13.

Alvarado celebrated the "7 Things" anniversary with a TikTok video.

"Hiiii yes! It’s me," Alvarado tweeted to Cyrus. "I now have 2-year-old daughter and I sing with my husband in @UsTheDuo. This was such a fun video to be a part of. Thanks for having me @MileyCyrus! Cheers to 13 years of this amazing song that I still know every word to! Sending love! xo."

As for the girl in the side ponytail? That's Hunter King, an actress who currently stars in The Bold and the Beautiful and The Young and the Restless. King was also featured in the 2009 Hannah Montana episode "Judge Me Tender," in which she played Bridget.

Mackenzie Stith, the girl holding an elephant plush in the video, also responded to Cyrus' tweet. "Hayooo. Still in LA. Acting in commercials and making some side cash on OnlyFans lol," she wrote.
