A few days ago Nicole Richie was seen shooting a video for Will Ferrell's comedy website FunnyOrDie.
Nicole, Joel Madden, Carmen Electra, Vanessa Hudgens and Lance Bass all came out to Zac Efron's pool party.
Producer Adam Shankman told press:
"We wanted to do something goofy including cast members, but it wasn’t a direct promotion. It’s very, very silly. It’s Zac Efron’s nightmare pool party where Tom Lennon and Nicole Sullivan, who are also in 17 Again play his white trash uncle and aunt and come and just humiliate him in front of a hip, young Hollywood crowd and they offend literally everybody in sight."
The video was released today.
