The actress, 23, attended the Children With Cancer Charity Ball at London's Grosvenor Hotel on Saturday night (9 November) in an unusual black dress with a large gold heart across her chest.
The little black dress with a difference was just Helen's style - classic with an eye-catching twist.
Choosing not to wear any accessories, the dazzling gold heart took pride of place on her outfit.
The dress couldn't have been more appropriate for the event, which was aimed to raise life-saving funds for young victims of cancer.
A champagne reception and three course dinner was followed by entertainment from Rollacoaster Big Band, Atila, West End Kids, The Romford Drum & Trumpet Corps and headliners Madness.
Fellow I'm A Celebrity contestant Charlie Brooker was also present.
