Sienna Miller: No Catfights with Savannah!

Sienna Miller leaves the Theatre Royal Haymarket after performing in Flare Path on Friday (June 3) in London, England.

The 29-year-old actress recently chatted about working with her older sis Savannah on their successful fashion line Twenty8Twelve.

“People always want to hear about some sort of catfight, but we couldn’t be closer,” she explained.

“We understand each other on a real level,” she added. “If we’re both in moods, we know there’s no need for communication. We read each other’s vibes.”

Savannah shared she feels the two “really are like each other’s other half. I feel as though I’m whole when I’m with her, which sounds ridiculous – my husband would be livid – but we create something that’s complete.”

FYI: Sienna is wearing a Twenty8Twelve vest.
