Classical singer Camilla Kerslake was centre of attention at Sunday's Olivier Awards after she suffered a wardrobe malfunction as she arrived with England rugby skipper boyfriend Chris Robshaw. Wearing a daring, backless black dress, Camilla, 26, showed off more than she bargained for in her revealing floor-length gown. Despite being accompanied by Robshaw, who played for Harlequins in their 29-26 Premiership victory over Gloucester 24 hours earlier, the cameras were firmly trained on the singer.

Daring: Camilla Kerslake showed off more than she bargained for in a daring backless gown at the Olivier Awards with MasterCard in London on Sunday where she was accompanied by Chris Robshaw . Posing with their arms around each other, the 'pre-engaged' couple looked the picture of happiness. 'Chris and I are on the same page and we definitely plan to get married in the near future,' the singer recently told The Mail on Sunday in her first interview about her famous boyfriend. 'Some people call it a pre-engagement. It's all about timing – at the moment we're both so busy with work. Pre-engaged: Camilla was joined by her England rugby captain boyfriend Chris Robshaw but her dress was the focus of attention . 'I even had to spend Valentine's Day outside in the cold sandwiched between hordes of angry men as I cheered Chris on during his game.' 'Pre-engagement' is a growing trend, with thousands of couples now choosing 'promise' rings ahead of a formal proposal. Camilla, though, has her eye on the real thing, and has been spotted scouting engagement rocks at Tiffany. Racy: Camilla flashed more than hint of sideboob in her dramatically racy floor-length gown . One way to get attention: Kerslake's dress made sure she stood out on the star-studded red carpet . So far, her  6ft 2in boyfriend has been notably reticent when friends have quizzed him on the subject. But Camilla appears undeterred. 'It's tricky now as I'm currently locked away in the studio recording my third album and Chris is obviously incredibly busy and focused on his rugby and the Six Nations. 'But he gets back from England camp in April and the Six Nations boys have some time off in May and weekends off in June, so we'll have more time to ourselves then,' she added. 'As soon as things calm down for both of us work-wise, we'll start making plans.' Tight game: Robshaw (not pictured) played for his club Harlequins against Gloucester on Saturday .
