Kylie Minogue suspects her phone may have been hacked while she was suffering from breast cancer.
Speaking after she received an honorary degree from Anglia Ruskin University, Chelmsford, the singer spoke of the challenges of fighting the disease while in the spotlight.
She said being in the public eye had been a "blessing" because of the support she received but a "curse" because of occasional media intrusion.
Asked if her phone had been hacked, she added: "It may have been."
She did not comment further on her suspicions but said: "Cancer is like going into war and you have to draw on everything you've got to fight it.
"Fighting the disease in the spotlight was both a blessing and a curse.
"A curse because of the constant attention and the press sometimes wanting more information than you want to give, but a blessing because of the love and support I received from complete strangers."
The singer was diagnosed with breast cancer in 2005 and underwent surgery and chemotherapy to beat the disease.
She was given the all-clear the following year.
Minogue received an honorary Doctor of Health Sciences for her work to promote cancer awareness.
