Bosses at Next Models in London have added The Saturdays star to their books alongside a host of fashionable faces.
The blonde beauty says, "When I was approached by Next, I was so surprised, so excited. I feel really flattered to be placed alongside the names they already have, it's incredible. I'm used to having the girls around me, so it is a bit scary to be doing things on my own, but they were all so excited for me. I'm really looking forward to the next step."
As well as style icon Chung and Burberry model Waterhouse, who is dating Hollywood star Bradley Cooper, Next Models also represents singer King's fellow pop stars Rita Ora and Lana Del Rey, as well as model Alice Dellal.
King already has connections to the fashion world - she's previously dated top male model David Gandy.
