Im doing my best.
Needless to say, her new co-workers dont respond too kindly to her at first.
Shes kind of having fun messing with everybody.

The fact that Donna cant quite put her finger on Samantha is really fun to play, Heigl says.
And shes not apologetic at all, which I kind of love.
Shes hoping fans will love it too.
