Robbie laughed off claims his song sounds similar to a prominent television advert for Haribo sweets.

The Haribo advert sounds like ring-a-ring of roses so it does sound like the Haribo advert, yes you're right, but they can't sue me because they also sound like a nursery rhyme from a couple of centuries ago."

Robbie said: "It was pointed out to me via YouTube when I read the comments and I was like 'oh yeah, it does doesn't it?' but I think every song has been written now and everything sounds similar."
