O'Connor and his siblings spent the weekend grieving the loss of their mother.
"Right now we are spending time together as a family and grieving together," he said. "It's important to be together.
"We have so many fond memories of our mum and want to cherish them," he said.
"We are still coming to terms with what has happened."
