My clean method is not passing, what could be the problem?

from django import forms


def not_treehouse(value):
    if value.lower().endswith('@teamtreehouse.com'):
        raise forms.ValidationError('Just come talk to me')


class LeadShareForm(forms.Form):
    email = forms.EmailField(validators=[not_treehouse])
    email2 = forms.EmailField(label='Email again', validators=[not_treehouse])
    link = forms.URLField()
    honeypot = forms.CharField(widget=forms.HiddenInput, required=False)

    def clean_honeypot(self):
        honey = self.cleaned_data['honeypot']
        if len(honey):
            raise forms.ValidationError('Bad robot!')
        return honey


    def clean(self):
        clean_data = super().clean()
        email = cleaned_data.get("email")
        email2 = cleaned_data.get("email2")
        if email != email2:
            raise forms.ValidationError("You need to enter the same email in both fields!")
