Justin Theroux Supports Sienna Miller at International Medical Corps Event

Sienna Miller walks the red carpet at the International Medical Corps’ Summer Cocktail Event held at Milk Studios on Tuesday (June 12) in New York City.

The 36-year-old actress has been a global ambassador for the organization since 2009 and she joined President & CEO Nancy Aossey at the event.

Sienna‘s friend Justin Theroux showed up to support the organization and his pal.

Last week, Sienna and Justin were spotted hanging out at a magazine party and they spent time together in France in late May while there for the Louis Vuitton show.

FYI: Sienna is wearing a Sonia Rykiel dress.
