Laura, who took over Caroline’s hosting duties, took to Twitter to say she couldn’t find the words to comment on her friend’s death.
She told her 379,900 followers: “I’m trying to find the words but I can’t,” alongside a photo of Caroline hugging her.
Laura also posted a poem which read: “To lose someone so special is really hard to bear, it hardly seems believable that you’re no longer there.
“You left us far too early before you time, it seems, and now you’ll never have the chance to fulfil all those dreams.
