On Saturday we wished Jourdan Dunn a happy 23rd, but another milestone model birthday took place too. That’s right, this weekend Jourdan Dunn and her best friend and ‘twin’ Karlie Kloss raised a toast as Jourdan marked another year and Karlie reached the legal drinking age in her native USA. The 21-year-old was joined by friends and family at a swanky soiree organised by fashion writer Derek Blasberg at the recently refurbished Paramount Hotel in Times Square, where she guests included fellow models Tyra Banks, Joan Smalls, Cara Delevingne and Chanel Iman, as well as designer Cynthia Rowley, actress Emma Watson and Karlie’s boyfriend Joshua Kushner.

While the party may have drawn a who’s who of the fashion industry, guests of honour were KK’s close family who flew in from the Midwest where both she and Blasberg hail from. The model’s mum, dad, sisters Kristine, and twins Kimberly and Kariann and even Grannie Stella were there to watch the supermodel blow out 21 candles, wheel out two giant Karlie’s Kookies and hit the dancefloor with her famous pals from Emma Watson to Tyra Banks.

Blasberg said of Kloss on his blog: ‘Despite logging in more frequent flyer miles than even I can count in the past seven years, she has maintained a sweet charm that has made her one of the most popular ladies in the business.’

After the bash, Karlie visited Disneyland with her fam. The group wore matching Minnie Mouse ears in family photos taken at the themepark and Karlie revealed that she kicked off the day with ‘birthday balloons and breakfast in bed’. She also shared a tender father-daughter moment with her dad Kurt Kloss and captioned a pic: ‘I love you daddy. thank you for 21 years of love ❤ #DaddysLittleGirl’. Fashion’s equivalent of the Kardashians are so cute!

As well as celebrating her own birthday, Karlie also took the time to wish Jourdan a happy birthday too. She tweeted, ‘Happy Birthday to my birthday twin and Best Friend in the Whole Wide World @officialjdunn #JourlieForever’ while Dunn returned the favour with the message: ‘HAPPY BIRTHDAY TO ME AND MY OTHER HALF MY LOVER, MY SIS, MY EVERYTHING @karliekloss love ya babes!!!! #teamleowedabest’.
