Gabriella Cilmi is joining British stars including singer Alexandra Burke for a trek along the Inca Trail in aid of a breast cancer charity.
The Sweet About Me hitmaker has signed up for the gruelling hike to the ruins at MAChu Picchu in Peru later this month (Sep10).
The all-girl group, which also includes British TV presenters Denise van Outen and Holly Willoughby, and radio DJ Fearne Cotton, will face intense heat in the day and sub-zero temperatures at night on the trek along remote mountain paths 4,000 metres (13,124 feet) above sea level.
Cilmi and her colleagues are raising funds for the Breast Cancer Care charity on the expedition, which begins on 24 September (10).
The Aussie singer writes on the organisation's website, "I am so excited to be joining the girls and I can't wait to get out there and meet everyone. I know it's going to be tough and emotional but I've always wanted to go to MAChu Picchu and Breast Cancer Care is a charity very close to my heart so this is a trip of a lifetime for me.
"Breast cancer has touched my family and I am already racking my brains for ways to raise as much money as possible so they can continue their brilliant work supporting people with breast cancer."
