Who ya callin' Kimbo?!

Kim Kardashian chatted on her cell as she left a photoshoot at Milk Studios in LA last night, and we have a feeling she was talking to team of personal assistants. Why, you ask? Because she's being driven in a Honda! The reality star is used to rolling around in Bentleys, not Uber X's, so someone's got some explaining to do.

The reality star was doing a secret project with little sister Kylie, and the two engaged in a friendly Snapchat war on set. The LipKit mogul applied funky filters to her sibling's face without her knowing, and so the mother-of-two retaliated by poking fun at the 19-year-old's massive lips.

Way to cut deep, KK!
