Kimora Lee has quit her role at the clothing company set up by her ex-husband Russell Simmons.
The reality TV star carved out a career in fashion by joining Simmons' Phat Farm firm and designing for the Baby Phat brand.
She stayed on as creative director after the company was sold in 2004 as part of a massive $140 million (£93.3 million) deal, but she has now quit to pursue other fashion projects.
Lee says in a statement, "It's time for me to move on and further expand my other businesses and create a new phenomenon. I adore all those who have faithfully been with me since the beginning. I'm forever dedicated to my family, fans, and customers."
