What's true for New England weather also applies to Rihanna's hair color. If at any moment you're not happy with it, just wait five minutes.

This weekend, as she blew threw England, promoting her new fragrance, Reb'l Fleur and performing at the V Festival, RiRi debuted a brand new shade of tresses: natural brown. This latest hue marks the singer's 14th follicle change-up since November 2010, according to stalwart investigative journalism undertaken earlier this month by the Daily Mail.

Not that fans at the V Festival were paying much attention to Rihanna's 'do. As the Daily Mail reports today, the big story at Hylands Park on Sunday (Aug. 21) was the bodacious Barbadian's outfit: a barely-there hotpants-and-denim-shirt combo.

Performing a day earlier, Rihanna rocked a punk-style black leather jacket and cutoff Union Jack top, getting the crowd good and warmed up for Saturday headliner Eminem.

"#VFESTDay1 I LOVE YOU!!!" the newly brunette diva tweeted after leaving the stage. "80'000 screaming rockstars!!! I can't wait to see Eminem!!!!" The Bajan songstress joined Slim Shady during his performance at the festival when he began their collaboration, 'Love the Way You Lie.'
