Vanessa Hudgens Movie Premieres

Vanessa Hudgens showed up on the red carpet for the premiere of Sucker Punch without a date last night - she is single, after all - but not without her sense of fashion.

The event took place at Grauman's Chinese Theatre in Los Angeles, as young actresses from across Hollywood showed up to help promote a thriller that features Hudgens, Emily Browning, Abbie Cornish, Jena Malone and others.

Emma Roberts was also on hand, looking sharp. Below, we're asking fans to contrast this Scream 4 star with the former High School Musical student...

It's a week of beautiful couples on the red carpet.
