The former Miss World took to the catwalk with model and burlesque dancer Dita Von Teese in gowns made entirely from biscuit wrappers.
The two beauties took to the catwalk in the creations on Monday night at an event in Cologne, Germany, sponsored by Lambertz biscuit-makers.
Known for her 1940s style, Dita was outdone by Rosanna who with her long legs and blonde locks, managed look good in the red plastic creation. But it was straight back to the books for the recently engaged model as she studies to become a nutritional therapist.
"College assignments will be the death of me," said a glum Rosanna yesterday and she was immediately inundated with messages of support from her followers on Twitter.
