Michelle joins US actresses Julianna Margulies (The Good Wife), Claire Danes (Homeland - our new fave) and Sophia Vergara (Modern Family) - and none of them appear to be wearing an awful lot in the way of clothing...

It all serves to prove quite how popular Dockery has become across the pond, finding fame as Lady Mary Crawley in the award-winning series.
And rightly so, we say.

Feeling envious of Michelle's impossibly glossy locks? Yes, us too...
- Angelina Jolie<p> Hollywood beauty Angelina Jolie kept her locks light and fresh at The Tourist premiere with some dark blonde lowlights, creating an overall soft-brown finish. She added drama with her signature feline eyes and some clever backcombing.</p>

- Anne Hathaway<p> Bride Wars star Anne Hathaway softened her chocolate-coloured hair with some soft amber highlights, which were beautifully enhanced by her apricot lips at the Love and Other Drugs premiere in New York.</p>

- Daisy Lowe<p> The MyDaily launch party saw a host of celebs come to celebrate with us – and we adored Daisy Lowe's soft eye-skimming fringe and tousled chocolate curls.</p>

- Kate Middleton<p> Kate Middleton's <span style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; line-height: 17px; text-align: left; ">signature luscious locks were curled and polished, and her make-up was flawless when attending <em>War Horse</em> premiere.</span></p>

- Katie Holmes<p> This might be one of our all-time favourite Katie Holmes hairstyles! From the warm red undertones and high-shine glamour, to the big bouncy curls, we fell head over heels for this look, which she showed off at the Golden Globe Awards in 2010.</p>

- Kelly Brook<p> Curl power! Kelly Brook may well be one of the most glamorous brunettes in our round-up. And she was on sparkling form as ever when she stepped out at the Prince's Trust Rock Gala in 2010 with pumped-up tendrils showing a hint of a reddish glow. Love the matching peachy lips.</p>

- Kiera Knightley<p> At the Rome International Film Festival, Keira Knightley's face-framing mid-brown bob was the perfect colour-match for her deep brown eyes, while the loose kinks worked to soften her beautifully angular features.</p>

- Kylie Minogue<p> </p> <p> Kylie Minogue and her<span style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; line-height: 17px; text-align: left; "> glossy chocolate brown locks at the <em>Cosmo Women of the year Awards.</em></span></p>

- Mila Kunis<p> </p> <p> <span style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; line-height: 17px; text-align: left; ">Mila's makeup complimented her honey toned low-lights perfectly and there was no denying that the star looked gorgeous at a </span><span style="font-family: Helvetica, Arial, sans-serif; line-height: 18px; text-align: left; ">children's research hospital benefit gala.</span></p>

- Olivia Wilde<p> </p> <p> <span style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; line-height: 17px; text-align: left; ">The actress swapped her long auburn locks for a</span><span style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; line-height: 17px; text-align: left; "> shorter, two-tone waves hairstyle. </span></p>

- Rachel Bilson<p> Rachel Bilson was one of the first celebrities to channel the two-tone trend. The stunning actress's long layers went from mahogany to blonde-brown, and finished with a slight – yet body-building – curl. Gorgeous.</p>
