Elton and Gordon Ramsay have joined a new class action lawsuit against the publisher of The Sun and defunct News of the World over an alleged phone-hacking scandal.
They are among 63 alleged victims who have issued a bid for compensation at the High Court in London.
Bosses at News Group Newspapers already faced claims from 28 people who also allege their voicemails were hacked during a ruthless and unethical news-gathering campaign, which led to the closure of the News of the World in 2011.
More than 1,000 people, including Hugh Grant and Charlotte Church, have already settled with the company. But other cases - including actor David Tennant - are still being heard.
Christopher Hutchings of Hamlins Solicitors, the lead firm for the 91 claimants, said that the recent inclusion of The Sun had led to more alleged victims coming forward.
He added that some claimants were seeking damages for "concealment and destruction of evidence" by News Group Newspapers.
