No one tells Olivia Palermo what to do -- or what to wear. On 'The City' (Tue., 10:30PM ET on MTV), Olivia defied her boss at 'Elle' magazine, refusing to wear some assigned designer duds to a magazine event.

"My name is on an invitation to host a party for 'Elle' magazine," boss Joe Zee said to Olivia and coworker Erin Kaplan. "I just expected that both of you would show up, support me, support the magazine, but also support the designer."

In a patronizing tone, Olivia responded, "Oh, Joe," and appeared to be stifling a laugh. "I just want you to know how serious this situation is," said Joe. "Mm, yeah," she said with a smirk.
