'It feels like it's been a really traumatic year and a half, almost two years at this point. It's a cruel disease and I know many people suffer with it. We definitely lost a great one there.'
Nadine also spoke of how close the pair were and said they remained in touch long after Girls Aloud went their separate ways.
She said: 'She was unbelievable. Me and Sarah have been close and always remained close. We were a great support for each other in the band and for years after.'
Nadine recently took part in the new Irish musical talent show Last Singer Standing and said she felt like she received signs from Sarah during filming.

She said: 'I was so close to her in life. There's definitely been things, she's made her presence known a few times. As I was shooting the show, it was right in the middle of it all and people were being so kind.
'There was a couple of days when the headphones just flew across the table and it happened three days in a row and the makeup girls were saying, "that has to be Sarah."
'One night I was taking about me in my house and something flew off the shelf. I was like, "Is this Sarah?" I'm still thinking she's going to phone.'
Nadine told how the filming schedule for the show was already set when she heard the news of Sarah's passing.
She said: 'The show was scheduled, everything was booked. There was no way they could take a break for me to grieve. It was straight back into work. Everyone was so kind and patient with me, it was great. '
