It’s not often that Kristen Stewart pops up on Instagram, but the actress has been snapped alongside her Camp X-Ray co-stars Lane Garrison and Peyman Moaadi. K-Stew is currently shooting the film about a soldier assigned to Guantanamo Bay and unsurprisingly there are already whispers of a romance with shaved headed hunk Garrison. The actor, who is best known for playing the role of David “Tweener” Apolskis on the television series Prison Break has somewhat of a past having been found guilty of vehicular manslaughter in 2007 and arrested for misdemeanor battery for allegedly hitting his ex girlfriend last year. Despite Internet speculation we doubt that K-Stew is really eyeing up her colleague, but she certainly looks more smiley than she has done since her break up with Twilight hunk Robert Pattinson earlier this year.

Meanwhile there’s no doubt that Nicole Richie and Joel Madden have the hots for each other. The couple and their two children Harlow and Sparrow are currently enjoying a European vacation and by the looks of their Instagram photos Mr. and Mrs. Madden-Richie are more besotted than ever. Nicole revealed a pic of herself and her man in an Italian harbour with the caption “Love in Portofino”, while Joel shared a snap of his wife and kids, titled “Seeing my dreams”.

And finally, Girls star Lena Dunham has been having some fun with her boyfriend Jack Antonoff (of American band Fun) and his sister, designer Rachel Antonoff. The trio wore matching doggy jumpers as they dined in New York.

The Kardashian family celebrated Penelope Disick’s first birthday earlier this week in their typical style – lavishly. Famed for throwing extravagant bashes, from their annual Christmas Eve party to Kim’s outdoor baby shower earlier this year, Kris Jenner and her children planned a birthday to remember (which she probably won’t) for Kourtney’s daughter including over 150 guests and 30 3ft balloons in light pink, rose and cream from Geronimo.

Party planner Sharon Sachs was behind the bash, which took place at grandparents Kris and Bruce Jenner’s Los Angeles home. Reportedly Kim Kardashian and Kanye West and their daughter North were among the family and friends in attendance, although the couple stayed in the house for most of the afternoon as a source revealed, “She’s too little to be around that many people”. Along with the helium wonders, Penelope’s “Major balloon party” also featured a country fair complete with baby animals and a unicorn. Only in Kardashian world! In the past the family have marked family occasions with bowling trips, pyjama parties and fancy dress.

While Penelope’s actual birthday was on July 8th, the party took place on Sunday. Then on Monday Kourtney and her partner Scott surprised Penelope and her three-year-old brother Mason with a trip to Disneyland, but by the looks of Kourtney’s Instagram pictures she enjoyed the experience as much as her children. She posted a photo of a Disneyland firework display, with the caption, “Magical Monday night at my home away from home. #Disneyland #movingin”. Scott has been having some fun of his own after treating himself to a yellow Rolls Royce. Kendall Jenner revealed a photo of the flashy car along with the sarcastic tweet, “super low-key @letthelordbewithyou #Gatsby”.

1. Reem Kanj’s fashion diary in pictures

My week started off with another trip, this time to Austria to visit the Silhouette head office with Tank Magazine. I also started juicing, it’s definitely been an experience and my kitchen has never looked so healthy! The weather is fabulous in London (finally) I just wish I had more time to enjoy it, but luckily for me one of my best friends is back in town and staying with me so being at home is far from boring right now. 

‘For my millionth time at the airport this month, I opted to stay cool and comfortable in Zara and Sam Edelman.’

We’ve all had a waddle and a peek into our mum’s closets when we were younger, smearing lipstick and stepping into oversized shoes we could only ever hope to grow into. Today, childhood dreams come true with the most iconic of mother’s – Diane Von Furstenberg – opening up her closet doors for all those wide eyes to feast on. 

Visual project ‘Playing in Diane’s Closet’ launches today, giving fans a peek into Diane’s iconic archive for the first time. Using both vintage and current DVF pieces, along with Diane’s personal collection, a unique film and set of images have been created by blogger and fashion consultant Natalie Joos of Tales of Endearment. The photo shoot and film, shot in Cloudwalk – Diane’s home in Conneticut, features modern day DVF muses Lisa Love, Eizabeth Gilpin and British model Tali Lennox. 

“It’s hard not to go a little ga-ga over this shoot. Did I mention I am the first person EVER to have accessed Diane’s archives Not even her own granddaughter Talita who’s visiting, knew of their existence,” gushed Natalie Joos.

“She stares in awe at the trunks of clothes we unload from the van: Giorgio di Sant’ Angelo skirts, vintage Louboutin heels, nameless red fringe pants, vintage DVF fur boots, wrap dresses in different patterns, accessories from the new collections, Stetson hats; they’re all about to come alive on camera” she adds.

The drool-worthy, often one-of-a-kind items are unveiled in the run up to the Autumn Winter 2013 collection and the 40th anniversary of the iconic wrap dress. Asked what it was about the dress that made it so famous, Furstenburg replied: “I think the thing that made it special and that has made it timeless is that it was all about the woman. It really flattered a woman’s body and it gave her independence and power… and that it still so relevant today.” High five to that!

It just gets better and better. Following a glimpse at Jennifer Garner’s foray onto fashion territory with her debut modelling campaign for Max Mara, and a behind the scenes glimpse at Rag & Bone’s forthcoming endeavour, Carla Bruni-Sarkozy today makes her return to modelling with Bulgari’s ‘Diva’ campaign, shot by none other than the legendary Terry Richardson.

Following hints earlier this year that the singer, turned model, turned First Lady of France would be making a return to the glossy pages once her husband Nicolas Sarkozy was no longer in office, pictures have today emerged showcasing the Italian-born beauty bedecked in Bulgari for the forthcoming campaign.

“Bulgari is for me the symbol of passion and of this vivid and colourful Roman gaiety,” said Bruni-Sarkozy, going on to reminisce about a Bulgari bracelet that had once belonged to her aunt: “I loved that bracelet, I loved its joy, its fantasy. I dreamed of one day possessing such a wonder of my own! I was told that like me it came from Italy to Paris. Perhaps that was part of why I loved it too. I later discovered that the treasure I so coveted came from Bulgari… Is it chance or this bracelet that brought us together”

Bruni-Sarkozy has previously modelled for the likes of Dior, Yves Saint Laurent and Chanel, before quitting to work on her musical aspirations. She did equally well in both realms, selling two million copies of her debut album, which was released in 1999, but we’re delighted to see her back to her posing best. And doesn’t she look glam!
