Looks like Cameron Diaz has had a busy week (but don’t all celebs?). After winning an Environmental Media Award for her show Trippin’, she surprised a class at Stanford University when she helped lead a lecture on environmentally friendly design with enviro celebrity William McDonough.

Her appearance is part of mtvU’s “Stand-In: Who’s Coming To Your Class?” which will be premiering on mtvU Uber on Nov. 1st.

What is mtvU Uber you ask? Like Current TV and Participate.net, members of the mtvU community can help shape news and other content by submitting videos online:

“With today’s announcement, we are handing over an entire channel online to college students and everyone who wants new music,” said Stephen Friedman, GM, mtvU. “mtvU Uber gives them the power to create and program their own channel, and will remain in perpetual beta mode as they experiment and pioneer the digital future.”

Grist thanks its sponsors. Become one.

If you thought Cameron Diaz leading a class on eco-friendly design sounds a little odd, just imagine Marilyn Manson teaching little Johnny and Suzie Arts in Society!
