Hayden Panettiere @ 'It's a Mall World' Premiere

Hayden Panettiere comes out to support Heroes co-star Milo Ventimiglia at the premiere of It’s A Mall World at the ArcLight Theatre on Tuesday in Hollywood.

Milo is the director of a comedic mini web-series called It’s a Mall World as part of a marketing campaign for American Eagle Outfitters.

The 17-year-old singer/actress wore an black-and-white striped strapless dress by Alice + Olivia and accessorized with peep-toe shoes and an interestingly shaped white handbag on her wrist.
