The singer took to twitter today to reveal that she is the new spokesperson for Herbal Essences. She posted the picture above with the caption, "Thrilled to announce I'm @herbalessences new spokeswoman! Can't wait for you to see the new ad we shot!"
We're yet to see the new ad campaign, but we're guessing that her long, raven locks will be glossier than ever before. We'll keep you posted but in the meantime, take a look below for more celebrity hair inspiration and see the full picture of Nicole at Nicole Scherzinger on WhoSay.
- Blake Lively<p> The <em>Gossip Girl</em> is blessed with glossy, honey toned hair but it's at its best when worn with a soft wave. Avoid limp locks by adding a light curl through long hair to add volume and texture. Serena van der Woodsen eat your heart out.</p>

- Demi Moore<p> Demi Moore is the queen of ultra sleek, long hair. She also wins in the shine stakes too (we would love to know her secret). Use a protective spray before using straighteners to keep your long locks looking healthy.</p>

- Kate Hudson<p> Blonde bombshell Hudson proves that poker straight hair doesn't have to be boring. Follow her example and add a long, side swept fringe to add shape and definition.</p>

- Kate Middleton<p> With the whole world keeping a close eye on her, Kate Middleton is the leader of the long hair pack. Kate keeps her hair looking natural and healthy, often by adding tousled waves. Most importantly, her bruntette locks are frizz free (she is a duchess after all).</p>

- Kim Kardashian<p> Kim Kardashian is never seen with a hair out of place. (What would you expect from a Hollywood star?). Her smooth, silky tresses are long without looking heavy and if you're wondering how to master her look, there's always the option of adding extensions to thicken out the hair, Kardashian style.</p> <p> </p> <p> </p>

- Megan Fox<p> The beautiful brunette oozes Hollywood glamour on the red carpet, helped along by her long, flowing locks. Her side parting and textured waves emphasise that sexy, sultry look that Fox is so famous for. Wear with smoky, black eyeliner and a rose coloured lip gloss à la Megan.</p>

- Nicole Scherzinger<p> The <em>X Factor</em> star rivals Beyoncé's flowing mane. Scherzinger often keeps her thick, black hair super straight, but the heavy curl gives it an extra glossy, glamorous look.</p>

- Penelope Cruz<p> When she's not sporting a chic updo, Cruz's long hair creates that effortless, natural look that the actress always pulls off. Long locks don't have to be overly styled to look A-lister good.</p>

- Sarah Jessica Parker<p> SJP looks her best with tousled, beach-chic waves in her long hair. Avoid the flat, dull look by using rollers to create the curl, then finish with a fixing spray to add shine and avoid any frizz.</p>

- Beyonce<p> From glossy, sleek locks to sexy, tousled waves, Beyoncé is famous for her fabulous long hair. No matter which way she wears it, the singer knows how to work it. Where would she be without her crazy curls when she's rocking out on stage?</p>
