Pixie Lott oozes class as she steps out in Rome wearing an elegant black dress

She was one of a host of famous faces invited to the star-studded wedding of Princess Diana's niece Lady Kitty Spencer, 30.

And Pixie Lott, 30, oozed class as she stepped out of her hotel in Rome on Saturday and headed to the wedding ceremony with her fiancé Oliver Cheshire, 33.

The singer dressed up to the nines in an elegant black gown as she made her way through the Italian capital to the wedding at Villa Aldobrandini in Frascati.

Pixie looked sensational in an all-black lace dress, featuring intricate floral patterns all over.

Wearing her hair back in a slick-wet look, she also wore large diamond earrings and a single necklace as she travelled with her beau Oliver.

She added height to her ensemble with a pair of chunky heels and she also carried a small black leather handbag.

Meanwhile, Oliver looked dapper as he stepped out in a sleek black tux, complete with a crisp white shirt, a black waistcoat and a black bow tie. 

As the couple emerged from their hotel, Oliver was spotted wearing a pair of sunglasses as they made their way to their taxi. 

Pixie and Oliver were among a host of glamorous guests at Kitty's nuptials including the bride's sisters, twins Eliza and Amelia; Viscountess Emma Weymouth and her husband Ceawlin Thynn, the Marquess of Bath; Idris Elba's wife Sabrina; and Made In Chelsea star Mark Vandelli. 

Also present were 62-year-old Mr Lewis's three adult children from a previous marriage. 

Lady Kitty – the eldest child of Diana's brother Earl Spencer – is understood to have formed strong relationships with her South African-born husband's children.
