Well, she's half right.
What do you think of Jessie's new two-tone hair? Let us know below.
See more stars rocking a dip-dye here:
- Alexa Chung<p> The Queen of cool worked the dip-dye 'do at the 2010 British Fashion Awards, and fused chocolate-brown roots with bright blonde tips. We think it kinda works...</p>

- Caroline Flack<p> Caroline Flack shows off her two-tone blonde curls at Cosmo's Ultimate women of the year Awards.</p>

- Cat Deeley<p> <span style="font-size: 10pt; line-height: 12pt; ">The Brit beauty really tapped into the LA look at the 2011 People's Choice Awards, and worked two different colours through her beachy waves, with a look-at-me blonde giving way to a glowing brown base.</span></p>

- Dannii Minogue<p> Dannii worked two-tone tresses at the 2010 X Factor final press conference – and we thought she pulled off the daring look with aplomb. The stylish bob cut and glamorous matching lippie and dress combo helped to create a classy finish.</p>

- Drew Barrymore<p> Never one to shy away from a style statement, the Charlie's Angels star pretty much kicked off the dip-dye trend. </p>

- Jessie J<p> Jessie J debuted some long purple-tipped hair extensions at Capital FM's Jungle Bell Ball. </p>

- KT Tunstall<p> The singer worked the rock chick look at the Q Awards in London, toughening up a pretty plait with platinum tips.</p>

- Nicola Roberts<p> The Girls Aloud star showed off her new, longer hairstyle (and some very white teeth) at an event in London. We think this volumised, dip dye do is one of Nicola's best looks to date.</p>

- Rihanna<p> No stranger to wild and crazy hairdos, the singer was (of course) one of the first stars to sport the two-tone look at a 2010 pre-Grammy party in LA. She rocked a honey-blonde quiff with brown shaved sides for an unconventional, bold barnet.</p>

- Whitney Port<p> The City star showed off the barely-there dip-dye graduating her light brown roots into platinum waves. Pretty.</p>
