Heartbreaking.

Girls Aloud's Nadine Coyle has paid another tribute to her late bandmate Sarah Harding a week after her passing. Telling fans that Sarah was an "inspiration" and a "shining light", she shared pictures of the two together. Taking to Instagram, Nadine said: "One week without you!! Thinking of you all day everyday & trying to imagine how your new journey is going. Please feel free to come visit me anytime. "I know lots of people will want some Sarah spirit time so I can wait my turn. I hope you now know how much you are loved & how you impacted so many lives by being wholeheartedly yourself. "Always an inspiration, always a shining light & always my friend!!" Sarah passed away last Sunday after telling fans August last year that she had been diagnosed with breast cancer and that it had spread throughout her body. This was Nadine's second tribute to her late friend, initially sharing some touching words when the news broke of her passing. Nadine wrote last week: "I am absolutely devastated!! I can’t think of words that could possibly express how I feel about this girl & what she means to me!! "I know so many of you will be feeling this way. For now I’m sending so much love to you!!!" Sarah passed away last week, with her death announced on her Instagram page by her mum Marie, who wrote a heartbreaking statement. It read: "It’s with deep heartbreak that today I’m sharing the news that my beautiful daughter Sarah has sadly passed away. Many of you will know of Sarah’s battle with cancer and that she fought so strongly from her diagnosis until her last day. "She slipped away peacefully this morning. I’d like to thank everyone for their kind support over the past year. "It meant the world to Sarah and it gave her great strength and comfort to know she was loved. I know she won’t want to be remembered for her fight against this terrible disease – she was a bright shining star and I hope that’s how she can be remembered instead."
