In the latest development in the phone-hacking civil trial involving Mirror Group Newspapers, the former girlfriend of soccer star Rio Ferdinand said she felt “completely and utterly sickened” when the Sunday Mirror revealed their relationship.

“I’m a very private person,” Lauren Alcorn, a Virgin Atlantic flight attendant, was quoted as saying, according to the Guardian, which is one of the few British papers giving the scandal extensive coverage. “I’ve never, ever wanted to be in the public eye — even walking into court today is my worst nightmare.”

Alcorn said the Sunday Mirror expose that ran in January 2003 under the headline “Rio playing away” upended her life.

The phone-hacking scandal originally focused on the News of the World, which shut down in 2012 and paid millions in damages. It was owned by News Corp., which also owns The Post.

Since then, the hacking scandal has widened to include others. Four former editors of the Mirror Group were arrested by Scotland Yard in September 2013, including Tina Weaver, who was the editor of the Sunday Mirror from 2001 until she was let go in 2012.

David Sherborne, the lawyer representing eight hacking victims, told a London court that the phone hacking at the Sunday Mirror, Daily Mirror and Sunday People was “rife” and “utterly unprecedented” and reached to the very senior ranks at the company.

Guardian columnist Roy Greenslade said, “The Mirror Group phone hacking is not getting the headlines it deserves.”

Sherborne said the Mirror’s phone hacking started in 1999.

During that time, Daily News Editor-in-Chief Colin Myler and failed CNN talk show host Piers Morgan led Mirror newspapers accused of the hacking.

Neither has been charged.
