Keira Knightley has given us another glimpse of her diamond engagement ring at the première of her new film last night (June 18th).

She even brought some flower power to the red carpet of her latest movie ‘Seeking a Friend for the End of the World’.

Knightley wore a light tan Valentino gown complete with floral embroidery teamed with a maroon floral headdress.

She kept her make up simple with brown eye shadow and nude lips to complement her feminine gown.

Her only other accessory was her stunning engagement ring, which we saw for the first time on May 29th.

The Pirates of the Caribbean star is engaged to Klaxons keyboardist […name] after 15 months of dating, after being introduced by mutual friend Alexa Chung.

Since then, the couple have been very private and have never been pictured at a public event together.

Knightley appears in her new film with Steve Carrell, who plays a character looking for his high school sweetheart accompanied by her character.
