Jumping on the Internet-film bandwagon, <a href="https://okmagazine.com/search/efron" target="_blank"><strong>Zac Efron</strong></a> and gal-pal <a href="https://okmagazine.com/search/hudgens" target="_blank"><strong>Vanessa Hudgens</strong></a> spent a day earlier this week shooting a short film for web sensation <a href="http://funnyordie.com" target="_blank">FunnyOrDie.com</a>.

And now, <em>OK</em>! can reveal a few details surrounding the soon-to-be posted flick.

The March 31 shoot occurred at the Hollywood Hills home of Zac's Hairspray director Adam Shankman and, in addition to <a href="https://okmagazine.com/search/richie" target="_blank"><strong>Nicole Richie</strong></a>, co-stars Reno 911's Thomas Lennon as Zac's "Uncle Hank," who disrupts the HSM star's A-list party.

"It was a quick shoot and everyone had a blast!" an on-set source reveals to OK!.

Though it's ultimatey meant for Internet viewing, the short film will get its premiere in theaters as a lead-in to Zac's new film, 17 Again. The movie opens nationwide on April 17 and co-stars Matthew Perry.
