ASHTON KUTCHER made a surprise appearance on "Ellen" yesterday, and he dropped a bomb on her: He and his investment partner donated $4 MILLION to the Ellen DeGeneres Wildlife Fund.
That's the charity that PORTIA DE ROSSI set up for Ellen as a birthday gift earlier this year.
Ashton said, quote, "You're always thinking about everyone else and we wanted to show you that people are thinking about you."
