The Queen of Disco is their mom, but Mimi Sommer Dohler and her half-sisters, Brooklyn and Amanda Sudano, didn't grow up living the high life like many people assume.
While the late Donna Summer was on stage entertaining millions of people all over the globe with her chart-topping hits, her daughters were hidden from the limelight.
They spent a lot of time on the road, but unlike many other celebrity children who often have everything given to them on a silver platter, these girls had to learn the value of work.
"We were put to work," Brooklyn told The New York Post in 2017. "We had a few summers where we did that [grunt work]. Our parents wanted us to have an understanding of what it was like to put on a production."
While it may not have been exactly a fun way to spend summers, these girls are thankful that their parents thought didn't take it easy on them.
Like their mother, who died of cancer in 2012 at age 63, the sisters have grown up to become very successful adults with careers in the entertainment industry.
Mimi, 45, was born in Germany during Donna's first marriage to Austrian actor Helmeuth Sommer.
She grew up singing background vocals for her legendary mother, but later tried her hand at acting, though she isn't nearly as famous as her younger siblings.
She is currently married and has four children, including a daughter named Vienna, who seems to have inherited her grandmother's talent.
Brooklyn, the oldest of Donna's daughters with second husband Bruce Sudano, also chose acting over singing, and was able to find immense success.
She recently starred in the NBC show Taken, inspired by the Liam Neeson movie of the same name.
For two seasons, the 37-year-old played the role of Asha Flynn, an environmental lawyer trying to uncover the mystery behind her friend's death following a terrorist attack.
You might also recognize Brooklyn from Cuts as well as the ABC sitcom My Wife And Kids alongside Damon Wayans. She also worked as a model, starring in campaigns for brands like Clean and Clear, Clairol, and K-Mart.
Prior to taking up acting, Brooklyn attended Vanderbilt University before honing her craft at the Lee Strasberg Theatre and Film Institute in New York.
As for Donna's youngest, she is following in her mother's footsteps as a singer. Amanda started out as a model, appearing in ads for high-end brands like Louis Vuitton, but she is now most famous for being the one half of the successful folk-pop duo Johnnyswim.
Amanda and her husband Abner Ramirez formed their band in 2005 after she attended a songwriting workshop he hosted. The pair had met four years earlier during Sunday service at a church in Nashville, Tennessee.
They released their debut EP in 2008, and after the tying the knot the following year, the couple relocated to Los Angeles. They have since released several albums; their most recent, Georgica Pond, came out in 2016.
The duo have been touring all over the world, and in 2014, they gained even more popularity when Joanna Gaines announced that Johnnyswim's song "Home" would be the theme song for the hit HGTV show Fixer Upper.
Amanda and her husband are also proud parents to two children, a three-year-old son named Joaquin Emmanuel and a seven-month-old daughter Luna Bird.
Although Amanda, Brooklyn, and Mimi lead busy lives, they still have a close bond. Despite rumors that the sisters were torn apart over fighting for the fortune Donna left behind, the trio are occasionally seen together.
Last June, the sisters attended the 72nd Annual Tony Awards and introduced Summer: Donna Summer Musical, which is inspired by their iconic mother, of course.

"She [Donna] would be so happy for our success together," Amanda said of her mother while talking to The Grio. "We're following in the footsteps of her and my father. And no matter how successful we are, we still have each other."
