And on Saturday Pixie Lott completed her job as chief bridesmaid as she attended her sister’s big day at a church in Essex.
The 22-year-old looked the picture of elegance in her deep cream prom style dress, while managing to not upstage her sister who no doubt drew gasps in her strapless gown.

Falling just below her knees the dress highlighted her legs, which she often has on show and her sling-back open-toe heels gave her extra height.
Her blonde hair was pulled off her face in a stylish chignon and she wore her usual slightly flicked eye-liner to accentuate her almond shaped eyes.
