Peter Andre surprised a Marie Curie nurse with a special performance after learning she was a fan of his music

Peter also opened up about the memory of his late brother Andrew, who sadly passed away from kidney cancer during Christmas time in 2012, aged just 54.

He said: "I had read about the Marie Curie tree and thought it was a lovely idea. When the charity told me that one of their nurses was a fan I had to come down and visit. The work Marie Curie does is really important and people like Marie Barker and her colleagues are amazing. She's the real star of this show."

The former 'I'm A Celebrity... Get Me Out Of Here!' star says if he could see his sibling again, the one thing he'd want to do the most is spend Christmas with him, as they only did it once before due to them living far apart.

He shared: "I tweeted in memory of my brother Andrew. If I could turn back time my wish would be to spend another Christmas with him. We were never able to spend Christmas together as we were never in the same country at the same time. The only year we did was the year Andrew sadly died.

"He's always in my thoughts but especially at this time of year."

Marie said the surprise visit from her idol "made her year".

She said: "I was visiting the tree today to show my support to all the people who are affected by terminal illnesses this Christmas and never imagined I would be meeting Peter - it's made my year.

"As far as Christmas memories go, this one will take some beating.

"It was really touching to see him share a memory of Andrew. They clearly had such a strong bond.

"Christmas can be really tough for those dealing with grief but remembering the happy times you spent together, and focusing on the special memories really helps."
