Spill the tea, sis! Kim Kardashian and her former assistant, Stephanie Shepherd, took to Twitter on Monday, February 11, to dish about a fellow celeb, who’s, er, not so nice.

“One of my childhood idols was at my house for our Grammy party last night,” Steph wrote. “I mean I wanted to be this woman, she inspired me to move to LA and work in entertainment and she was so f—king rude to me … in my own home. What a bummer.” In response, Kim, 38, spilled, “Ohhhhh I know who this is,” with a ~scream~ emoji.

Of course, Kiki nearly broke the Internet (again), with fans begging the stars to at least give them a clue. “Omg! Who?” one person wrote. Another added, “Wow … warning shot fired! The next time this person disrespects her friend, the name WILL get dropped, [and] a reputation WILL be ruined.” A third and fourth, however, seemed to think they knew who the tweet was about. “It’s Mariah Carey, right?” someone said, while a second had their own opinion: “I bet it’s @JLo.”

The latter would come as a huge surprise, though, considering the reality star and “On the Floor” songstress have been hangin’ out lately. Back in December, Jennifer, 49, joined in on a movie night at Kim’s house, along with her sisters Kourtney and Khloé Kardashian, mom Kris Jenner and singer Sia. Uh, I guess our invite got lost in the mail? The group held a special screening of Jenn’s movie, Second Act.

“I’m having a movie night at my house,” Kim revealed on her Instagram Story at the time. “Never in my life would I have imagined that my idol would want to come have a movie night with me.”

In a series of videos, the KKW Beauty founder credited A.Rod‘s leading lady with her love of all things glam. “My inspiration for everything has been Jennifer Lopez,” she said. “I would try and see what shoes she’d wear, what makeup, what hair — I became obsessed with glam because of Jennifer.”

Welp, it’s safe to say we can probably scratch that name of the list of Hollywood A-lister’s in the running. In the meantime, we’ll be patiently waiting with our mugs in hand!
