Django Admin: how to display fields from two different models in same view?

My site makes use of Django's User Authentication User model and a custom UserProfile model to store some additional data (birthday, etc.). Is there a way to create a view in Django admin that weaves together fields from both the User and UserProfile models?

I suspect that this code snippet is not even close, but maybe it will help illustrate what I'm trying to do:

from django.contrib import admin
from django.contrib.auth.models import User
from userprofile.models import UserProfile


class UserProfileAdmin(admin.ModelAdmin):
    list_display = ('name', 'gender', 'User.email') #user.email creates the error - tried some variations here, but no luck.

admin.site.register(UserProfile, UserProfileAdmin)

Error message:

ImproperlyConfigured: UserProfileAdmin.list_display[2], 'User.email' is not a callable or an attribute of 'UserProfileAdmin' or found in the model 'UserProfile'.

Ultimately, I'm trying to create an admin view that has first & last name from UserProfile and email from User.
