The announcement was made during the 40th birthday celebrations of the Range Rover brand, at The Orangery, Kensington Palace, with McGovern revealing that the first project Victoria will get involved in is a Special Edition Range Rover Evoque.
"Victoria Beckham is a talented British fashion designer and is extremely knowledgeable about great design and trends," said Gerry McGovern.
"Victoria understands luxury products - she is a Range Rover fan and has been a Range Rover owner for many years. Her fashion business is now in its third year and her designs are loved by critics and bought by many of the most stylish women in the world. I believe this appointment adds a new dimension to my design team as we continue to design products to appeal to a wider audience."
"This is a very exciting collaboration. The classic British heritage of Range Rover and the effortless style, quality and beauty is something I truly admire and also what I hope to achieve with my own brand. I am honoured to take on this role and be part of the creative team," she added when speaking at the anniversary celebration.
