So with her pixie crop streaked blonde, the award-winning star must have thought that, once again, she would have the 'most elaborate hair' award all sewn up at Paris Fashion Week.
But she didn't count on Britain's most flamboyant designer Vivienne Westwood.
The 21-year-old had some fierce competition in the barnet department courtesy of the fashion maven and her models.
No shrinking violet, the flame-haired 68-year-old joined her girls, sporting a wild up'do as she stepped out to receive applause at the end of her spring/summer 2010 show.
To the tones of Sid Vicious' rendition of My Way, the erstwhile punk designer – once married to Sex Pistols manager Malcolm McLaren – presented her signature draped knitwear alongside tailored shorts and jackets in styles borrowed from menswear.
Vivienne's show was just one of many ports of call for Barbados-born Rihanna, who has become a firm fixture at the front rows of all the top shows at Paris' prêt-a-porter season.
Earlier that day, she joined Dita Von Teese, Bruce Willis and his wife Emma Heming to see the presentation of John Galliano's latest designs for Dior.
