Other mistake: When Andy is talking to Christian outside the fashion event at night, he says, "If it weren't for the stupid boyfriend I would have to whisk you away right here and now," except Andy has never mentioned that she had a boyfriend. (01:04:58)
Suggested correction: It's quite likely that Christian knows this without Andy telling him. He and Andy know some of the same people who are associated with "Runway" (later on, he reveals the plan for Miranda to be fired). He probably has "connections" and keeps up with gossip.
Other mistake: When Andy is walking by the fountain in Paris, her phone starts ringing. When she checks to see who it is, Miranda's name and number shows up; however, if you look closely, the phone is actually showing an outgoing call TO Miranda, not FROM Miranda.
