January Jones is the real Emma Frost (and does a good job)

"X-Men: First Class" producer Lauren Shuler Donner spoke to IAmRogue and cleared up the confusion regarding the other Emma Frost (played by Tahyna Tozzi) in "X-Men Origins: Wolverine." She also thinks Jones did a "pretty good job" in the role.

Donner: No, she’s Emma from First Class. That’s who she was and she’s the real Emma Frost. I think January did a pretty good job of portraying her.
So there is no connection between the First Class Emma Frost and the one we see in X-Men Origins: Wolverine?
Donner: No … not really, no.
