The Italian designer - who dressed the 'Call My Name' hitmaker for her appearance on talent show 'The Voice' on Saturday night (26.05.12) - believes the singer is an ideal person to wear his clothes because she is ''strong, confident and sexy''.
He said: ''Cheryl is the perfect Cavalli woman. Strong, confident and sexy.''
Roberto and Cheryl designed a custom-made outfit consisting of vibrant colours mixed with leopard print as well as waistcoat shapes from his spring/summer 2012 collection for the 28-year-old singer's performance on the BBC One show - and he found it a ''great pleasure'' to work with the brunette beauty.
He added to Vogue.co.uk: ''Cheryl and I have had a relationship for many years.
''It was a great pleasure to collaborate with her in designing an outfit, especially for her performance on 'The Voice'. We used the signature Cavalli Fantasia and leopard prints to create a show-stopping outfit that enhanced her high-octane performance.''
Roberto's love of the British star comes shortly after he slammed US Vogue magazine editor Anna Wintour and described American fashion as ''terrible'', so much so he admitted he ''almost can't look at it''.
He recently said: ''Just look at American fashion, which is almost fashion. It's terrible and you almost can't look at it, but it has been driven by a great journalist - Anna Wintour - who wants all women to be like her and to dress the way she does.''
