Fans were thrilled with the announcement, with one writing: "It's so wonderful seeing you, looking more beautiful as always."

A second added: "That smile. Seriously. It gets me every time. Olivia is looking absolutely radiant and beautiful!"

Whilst a third wrote: "Wishing you much-needed health repair. I’m devoting my nightly prayers to your health because you're a national treasure."

Olivia is currently continuing her fight against stage four breast cancer, the third time she has been diagnosed with the illness in the past 28 years.

The mother-of-one was first diagnosed with breast cancer in 1992. It later came back in 2013 and was only detected when she was involved in a car accident.

Speaking about the cancer's return in 2017, she told The Guardian last year: "It's been a part of my life for so long. I felt something was wrong. It's concerning when it comes back, but I thought: 'I'll get through it again.'"
