Rachel Stevens and Mark Wright made for a glamorous presenting team on Thursday, as they teamed up to host the annual Caudwell Children's Butterfly Ball – one of the most prestigious fundraising events in the British social calendar. The pair were overseeing proceedings on the night, being held at the Grosvenor House Hotel in central London.
Former S Club 7 star Rachel looked stunning in a gown which featured a nude mesh bodice with intricate beading and a floor-skimming royal blue skirt, while Mark was suited and booted in a tux, and his hair in his trademark style.

This year's event, which will see Lionel Richie headlining, is particularly momentous for the charity, as it marks 15 years since Caudwell Children was first set up.
Each year the Butterfly Ball attracts royalty, A-listers and some of the most influential businesspeople in the world. In 2014 the ball raised £2.5million in one night. Other stars who lined the purple carpet on the evening included The Saturday's Vanessa White, Bruce Forsyth, and former model Jodie Kidd.
Rachel has been an ambassador for the children's charity for the past decade, and was first introduced to Caudwell Children, which helps seriously ill children, ten years ago when she performed at another of their fundraising events.

Rachel and Mark first met on the Strictly Come Dancing live tour, and Rachel then contacted him and asked if he would lend a hand at hosting.
"It sounds like an unbelievable event and I'm just pleased that I can help such a worthy cause," Mark, the former TOWIE star, said.
Headlining act Lionel couldn't contain his excitement, telling HELLO! exclusively before the event: "This is going be a hoot. I'm used to playing arenas, but this will be up close and personal, so hang on to your seats because this is going to be wild."
Tito Jackson and Paul Potts will also be taking to the stage on the night.
