Sienna Miller & Jason Segel: Den Duo

Sienna Miller sits down for a business meeting with friends at The Den on Saturday (October 16) in Los Angeles.

The 28-year-old British actress lunched with her Factory Girl producer Holly Wiersma and How I Met Your Mother funnyman Jason Segel.

We wonder which project they’re working on together. Another drama? A comedy??

On Friday, Sienna hosted the grand opening of Esquire House LA in Los Angeles.

FYI: Sienna is wearing 7 For All Mankind Gummy Gwenevere jeans in Grey.
