If Sienna Miller still holds a grudge with Anna Wintour for calling her “toothy” then she certainly didn't show it last night.

The British actress accompanied the Vogue magazine editor on the red carpet at the premiere of The September Issue in New York.

Miller wore a stunning blue minidress and clear perspex framed glasses to the event, while Wintour showcased a more colourful number.

Actress Rennee Zellweger also showed off her new slim figure on the red carpet in a reflective orange frock.

The September Issue follows an issue of Vogue from conception to the newstands.
