Khloé Kardashian is the one Emblem3 wants!

Or so they claim in their hit song “Chloe (You're the One I Want),” which the three X Factor stars say is about the 29-year-old Kardashian sister.

“To be honest, it was inspired by that whole situation [with Khloé and her sisters Kourtney and Kim],” Keaton Stromberg, 17, tells Life & Style. “We hung out with them at the Kardashian Christmas party last year.”

Drew Chadwick, 21, further explains, “It was the day before we recorded the song. I sang her name in that spot, but we already had the whole song written and we needed a name. I sang her name and we kept it.”

And their music label, Syco Records, loved it. “It works really well,” Wesley Stromberg, 20, tells the mag. “[The people from our record company] thought the whole sister thing was genius.”

So what is the song — which features lyrics such as “Chloe, I know your sister turns everyone on / But you’re the one I want” — exactly about?

“A girl, Chloe, who isn’t the most popular girl in school, but her inner beauty runs circles around her outer beauty,” the group explained to Seventeen over the summer. “She’s super real, super cool, and you would rather hang out with her than with the girl everyone thinks is hot because you can be yourself around her.”

Khloé admitted that she has always stood out from her sisters for being bigger, taller and louder.

“I probably thought I was prettier before I entered the spotlight because being compared to somebody else every day does sort of beat up your spirit and soul,” she told Cosmopolitan UK earlier this year.

But she added that the negativity and constant comparisons to Kourtney, 34, and Kim, 33, made her stronger. “I’ve gained another level of confidence,” she said. “I’ve always known that I’m not Kim and I’m not Kourtney – I’ve always been OK with that.”

Be sure to catch Emblem3 when they go on their first headling tour, the 24-city #BandLife Tour, which kicks off Feb. 10 at House of Blues in Dallas and ends in LA's Club Nokia March 15.
