Lara Bingle has been dropped by her sponsor ROC Eyewear three weeks after tweeting a photo of herself in a pair of shades by Kiwi designer Karen Walker.
The Australian model and reality star, whose Network Ten show Being Lara Bingle continues to lose viewers, was contracted to wear only ROC designs as part of the deal.
Bingle's parting of ways with the Australian label means she will no longer design and promote her own range of sunglasses.
ROC Eyewear company director Jason Blank told News Limited newspapers the split was amicable.
"After two season ROC Eyewear and Lara Bingle have mutually agreed to part ways," Blank said.
The ratings for Being Lara Bingle in Australia have slumped since its debut on June 12, attracting just 463,000 on Tuesday night.
The series will finish next week in a one-hour finale.
Bingle was recently in New Zealand to shoot an ad for Air New Zealand narrated by Rhys Darby, in which she said the country was "cold" and "eerie".
