Late Late Show line-up: Ronan Keating, Mel B and Nicola Coughlan to appear on tonight’s show

The former Boyzone and Rollercoaster singer has been back in the headlines in recent weeks after Louis Walsh described Keating as a “p***k” on ITV reality show Celebrity Big Brother.

It is one of many times when Walsh has been outspoken about those who he previously worked with on the reality show, including Irish duo Jedward.

In audio from 2006 that has resurfaced and was obtained by The Sun, Keating can be heard saying how he had to sack the former Boyzone manager and described him as being “very jealous”.

“I've no respect for Louis because he has none for me. He was very jealous of me.

“I had to sack him because he wouldn't manage me. He's a very selfish character. It's bulls*** man. He's a bulls****er,” Keating said.

Mel B will also join host Patrick Kielty on the RTÉ show on Friday night.

Though she made her fortune as a member of one of the world’s most successful girl groups, the singer has spoken about how leaving her husband left her with nearly nothing to her name.

“I wasn't just emotionally and physically abused, there was all the financial abuse too,” she told the BBC earlier this month.

“I didn't realise that I didn't have as much money as I thought I had. So I literally had to eat humble pie, live with my mum,” she added.

Forced to move back in with her mother, Mel B recently revealed how she had finally managed to buy her own home after five years.

“All you survivors out there will know how emotional this moment is. 5 mins ago a man arrived at my door with a set of keys.

“They are the keys to my new home. A house I bought with the money I've worked bloody hard to pay for,” the singer said in an Instagram post.

Galway actress Nicola Coughlan is set to appear on the Late Late tonight, who is currently promoting her new TV show, Big Mood which will air on Channel 4.

In the show, Coughlan plays young playwright Maggie who has bipolar disorder. The programme follows her character through the highs and lows of the disorder.

Coughlan will also star in season three of Netflix’s hit show Bridgerton. Part one of the new season is set to land on May 16, where the storyline will follow Coughlan’s character, Penelope Featherington, and Colin, one of the Bridgerton brothers.

During a sneak preview event for the show last month, Coughlan described how Bridgerton changed her life.

“I think before Bridgerton, had I gone to Brazil, I could have just hopped around,” Coughlan said.

“Now I think that’s probably not the case. I’ve never felt more like Beyonce. They were like ‘we have security, we have this, you have a car’ and I was like ‘oh my god I’m so fancy’,” the actress added.
