Renn, who had graced magazine covers, including four international editions of Vogue, and walked in runway shows for top designers such as Jean-Paul Gaultier, is now one of the most successful plus-size models working today.
So it is ironic that at the top of her game, Renn appears to be getting thin again.
She's certainly not the first female celebrity to slim down as her popularity rises. Hollywood actresses like Nicole Kidman and Renee Zellweger are thinner than when they first became celebrities. Singer-actress Jennifer Hudson is the latest star to downsize with fame. The new spokeswoman for Weight Watchers, she made the cover of People magazine proclaiming, "My New Body. WOW! Size 16 to Size 6!"
How Renn's weight loss will affect her career remains to be seen.
"It just depends if she will keep clients with the fluctuation in size or if she is choosing to stay smaller than when she came out on the scene," Emme said. "Really it's an internal decision for her career between her and her agent."
Her fans will be waiting to see what she decides.
