Sydney Sweeney has got straight to work in Venice, roping in a pal to snap an impromptu photoshoot on board a water taxi.

The actress has jetted in for the 83rd Venice International Film Festival.

Whilst she doesn't have any film projects to promote at the annual film fest, she, like fellow Armani Beauty poster girl Kendall Jenner, will be walking red carpets and hitting parties in her role as global ambassador for the brand - the official sponsor of the festival.

Sydney dressed the part for her first full day in town on Thursday, emerging from her canalside hotel in a strapless white mini dress.

The chic star added shades and a black clutch bag as she made her way to a water taxi, where her friend promptly started snapping photos of the posing star.
