Canadian cutie Michael Cera and co-star Portia Doubleday pose with Portia’s dog at the premiere of Youth in Revolt in Los Angeles last night.

Call me crazy for asking what seems to be an obvious question, but why do people bring their dogs to premieres or other Hollywood events??  I imagine the flashing of the bulbs and the hysteria probably scares the sh*t out of the dogs and I’m sure the dogs are really unimpressed with the whole Hollywood scene to begin with.  Food, run, ball, poop.  That’s what interests dogs.

In the movie, Michael’s character sets some goals:

While his trailer trash parents teeter on the edge of divorce, Nick Twisp sets his sights on dream girl Sheeni Saunders, hoping that she’ll be the one to take away his virginity

The movie opens tomorrow in theatres.
