KEY POINTS:
Katie Holmes has been voted the Most Stylish Star of 2007 in a new poll conducted by America's OK! magazine.
The stunning actress, who is married to Tom Cruise, has transformed herself in recent months from her tomboy Dawson's Creek character Joey Potter into a sleek fashionista who is never uncomfortable on the red carpet.
One OK! writer said: "Katie Holmes has matured from teen queen into a pillar of fashion. This year her style was developed and fine-tuned, so much so that she came to be viewed in the same realm as legends like Jackie O, helping her cruise beyond the shadow of her husband and into an iconic realm of her own."
Katie was closely followed in second place by Grey's Anatomy star Katherine Heigl thanks to her "natural and timeless beauty".
Gwen Stefani - who is renowned for her unique sense of style and has found success with her own fashion line L.A.M.B - came third, while 33-year-old supermodel Kate Moss took fourth spot.
Umbrella singer Rihanna rounded out the top five.
