I'll admit, I don't know either of these two girls here other then a quick google search to see their line of work. But then it hit me like a ton of bricks,
Gwyneth Paltrow! The set up is too good. Since she's known for having a poor attitude, she could easily snub both Kali and Emily who then turn to get their revenge on the prissy actress! It's a two on one total squash as they humiliate Gwyneth until she's begging them to stop.
And, since I'm really no fan of Gwyneth myself, I'd hope they really give that stuck up blonde bimbo a lesson she would always remember yet try to forget.
Emilia Clarke was a great suggestion too.
