In the land of celebrity it was a week of new hair, with Diane Kruger, Lena Dunham and, of course, Kim Kardashian all posting their new looks on Instagram. Kim went for a shocking platinum do, while Lena and Diane both sported wigs for their new roles in Scandal and The Infiltrator respectively.
Elsewhere, Justin Timberlake proved he is the king of posting sweet photos dedicated to his wife, Jessica Biel. In his most recent snap on Instagram, he wished his wife of two years a happy birthday and wrote the following message "you make me smile 'til it hurts. I love you like crazy!"
Other important news included a previously unseen photo of Kate Moss being released, which was shared on Instagram by fashion photographers Mert & Marcus. It depicts a nude Kate from a shoot in 2012 but as always she looks completely fabulous.

Reese Witherspoon shares touching picture of her husband and little boy
Every day, I'm so thankful to have this amazing man as my partner. I would not be where I am in this life if I didn't have his constant encouragement and complete support. He changes diapers, makes carpool runs and always has time to give me a much needed pep talk...(He makes a really good latte too!) Starting today, the organization @LeanInOrg, which encourages women to #leanin and reach their goals at work and at home, is asking us to celebrate the men in our lives who love, help, and support us daily! Husband, dad, brother, grandpa do you have an example of a man who you are thankful for? Share a photo tagged with the hashtag #LeanInTogether. I want to see! (And don't they deserve it?!)
