LOUIS Walsh has been known to dish out critiques throughout on-screen on various talent shows.
But it seems the former X Factor star is one of those people who is the exact same on and off-air.
Louis, 71, has had a three decade spanning showbiz career having first managed the likes of Johnny Logan, Boyzone, and Westlife.
This was before he made his debut on television on the the Irish version of Popstars.
But it has not been plain sailing for the star as he has been engulfed in plenty of drama behind the scenes.
In honour of his appearance in Celebrity Big Brother, we take a look back at some of the biggest feuds and fallout's.

Ronan Keating
After hits like 'No Matter What', and 'Love Me For A Reason', in Boyzone, Ronan decided to broaden his horizons and move into acting work.
He previously appeared Paw Patrol movie and in the Australian flick Goddess.
But towards the star.
In a seeming dig at his former client, he confessed to on Ask Me Anything that he felt Ronan was "not an actor".

He then admitted: "Can we move on? I don’t manage him anymore... I’m not in the fan club.
"It’s an Irish thing, we tend to say it like it is. We have to be honest as well. Nothing wrong with it (shooting from the hip)."
Cheryl
Arguably his most famous feud was with Girls Aloud superstar Cheryl, which ran for a decade.
After the girl band rose to prominence on Popstars: The Rivals in 2022, Louis spectacularly fell out with all five members of the group.
This was after he labelled the girls fat, which caused Cheryl to hold the Irishman in disdain for years.
It sparked Cheryl’s lengthy disdain for the Irishman, who was the band’s original manager.
In 2010, Louis compared Cheryl to a peacock, accused her of believing the ITV series was “her show”.
He issued further taunts towards the 'Promise This' hitmaker on-air as he said she looked orange.
Chezza soon hit back as she exclaimed: "Louis is a silly old man looking for attention."
A year later, Cheryl later claimed that Louis only "took the cheques," in his role as manager for Girls Aloud.
He later hit back by saying: "I am a much better manager than she is a singer.
"She seems to be in the fashion business now, selling fake hairpieces, fake eyelashes, fake everything.”
As Cheryl returned to the X Factor in 2018, Louis finally put their long-running feud to bed.
He admitted: "If Cheryl comes back that’s fine.
"Look, we would agree to disagree on certain things but that’s what makes it good. We all get on."
Cat Deeley
This Morning presenter Cat Deeley fell foul of Louis Walsh when she suggested The X Factor should be taken off-air.
Cat, suggested that viewers had become bored of the format and she suggested that Simon Cowell could axe the show.
She previously said of X Factor: "I think every big show like that is cyclical, like Britain’s Got Talent or America’s Got Talent.
"It was Opportunity Knocks about 25 years ago – they are hugely successful and then people get bored, and then they put them away for a bit, then they miss them, then they bring them back."
But Louis soon hit back at the former SM:TV Live personality, as he suggested she was just bitter at not landing the hosting gig herself.
He previously told The Mirror: "I think the truth is that Cat would love to be hosting the show but we have already got Dermot [O'Leary] and he is the best in the business.
"She can stay on Sky 1 where nobody is watching..."
He added: "It is a bit of the green-eyed monster from Cat... Sorry Cat, we don’t need you."
Nicole Scherzinger
Ahead of the 2017 series of The X Factor, Louis was briefly caught up in a feud with fellow judge Nicole Scherzinger.
He claimed his Pussycat Dolls co-star had been lying about her birthday and was much older than what she was saying.
In an interview with Heat Magazine, he said: "She's hilarious, talented and gorgeous. She ticks every box.
"She may be out really late the night before filming but she's still on it."
He then couldn't help but take a playful swipe as he joked: "It's great that she can still do all of it at her age.
"Nobody knows what age she is, but she's older than she says she is."
But the smash-hit singer later hit back, as she admitted that she had not been fibbing about her real age.
She admitted: "I wish I was lying about my age, I have never lied about my age.

"I should have started lying a long time ago."
Not resisting temptation, she couldn't help but have a jab at Louis, saying: "I’m just really grateful that Louis is still with us, really grateful."
