Actress Sienna Miller has laughed off suggestions she will eventually turn her back on her Hollywood career to focus on her clothing line. The Alfie star launched Twenty8Twelve, her collection with sister Savannah, in 2007, and they hit the runway at London Fashion Week on Sunday to present their Fall '09 range.

But, despite the success of her stint as a fashion designer, Miller insists she has no plans to abandon her acting career.

She says, "I'm not giving up acting, I love acting. But I also love working with my sister. We've always been two sisters playing dress-up, ever since we were kids, and we're still doing it."

Sienna plays The Baroness in G.I. Joe: The Rise of Cobra; sure to be a summer blockbuster! Check out the trailer:
