David Bellamy has previously insisted they won't be taking Spears to court, but he admits he and his brother are now reconsidering their options and are in talks with lawyers over plagiarism claims.

He says, "We will without doubt take the appropriate legal action if our attorneys agree we've been ripped off. Surely there is more original stuff out there to do rather than rehash old titles."

A spokesperson for Britney Spears says, "If this is now a legal matter then I am afraid we would have nothing to say until our lawyers have been alerted."
