Elizabeth Hurley says she is thrilled to have set a new Guinness World Record.
The model and Evelyn Lauder of beauty brand Estee Lauder - were presented with an official certificate at the Empire State Building in New York over the weekend in recognition of Most Landmarks Illuminated for a Cause in 24 Hours.
The campaign saw 39 iconic places around the world bathed in pink to mark the start of Breast Cancer Awareness Month.
Hurley said: "We are thrilled to be creating a new Guinness World Record commemorating an important initiative started by Evelyn Lauder 11 years ago.
"It's an honour and privilege to travel around the world with Evelyn, illuminating landmarks in pink and sharing our awareness with everyone we meet.
"It's wonderful to see the global impact that these illuminated landmarks have, motivating women to see their doctors regularly, perform a monthly breast self exam, and get an annual mammogram if they're over the age of 40.
"Our goal is to spread this message to women in all corners of the world."
To officially inaugurate the new category, a minimum of 24 pre-approved landmarks needed to be illuminated in pink for at least 10 minutes in a 24-hour time period.
The effort began in Australia, with the illumination of Federation Square in Melbourne and the National Library of Australia in Canberra.
The Empire State Building, India's Taj Mahal and Tokyo Tower in Japan were among the other landmarks used.
