Singer Katherine Jenkins is on the couch with Piers Morgan

KATHERINE Jenkins is set to open her heart in an emotional TV interview next week.

The mezzo-soprano has filmed the in-depth chat for the new series of Piers Morgan: Life Stories.

The episode — set to air on October 24 — will see Katherine tell all to former newspaper editor Piers.

Katherine told the Post: "I wanted to do it, but I was a bit nervous. Piers's style is very intrusive and he doesn't really leave any stone un-turned.

"But in actual fact, once it was all done I realised I had enjoyed it.

"There were lots of tears, talking about some things that were hard to talk about, but in fact I think it might make a good show."

Neath-born Katherine filmed at The London Studios for three hours for the primetime show.

The 29-year-old singer — who is usually very protective of her privacy — is set to give fans a rare insight into her life.

Last year Katherine chose Britain's Got Talent judge Piers to confess she had taken drugs before becoming a recording artist.

She said: "Piers has become a friend of mine.

"I am still very protective about parts of my private life, so there are things I don't talk about.

"But I talked more in depth about what it was like losing my dad and getting the record deal and coping with everything that happens to me now."

Katherine was joined by her sister Laura and mum Susan, who were in the audience after they had also been interviewed by Piers for clips to be used in the show.

The show is due to air two days before the release of Katherine's new album Believe, which she recorded in LA.

Katherine said: "I think it's an interesting concept for a show in that it's about life stories. It's actually interviewing people from your family and friends – there's all of that as well as the usual stuff.

"When you're promoting an album you get maybe five minutes on a TV show, so you never really get to talk in-depth, whereas this is an hour-long programme, so I think people will get to know me better."

The show is on at 10pm on ITV1 on Saturday, October 24.
