Theroux, known for his fearless approach to interviews, found himself at the center of a bizarre feud with none other than comedian Ruby Wax.

In a surprising revelation, Ruby Wax shared that she had harbored intense dislike towards Louis Theroux, going as far as to prohibit her children from uttering his name.

During a podcast conversation in June 2023, Ruby confessed that Louis Theroux was, in her words, her 'nemesis', and that she had been filled with bitterness and anger towards him, particularly after having to present him with not one, but two BAFTA awards.

Ruby Wax's appearance on 'I'm A Celeb' in 2025 sparked renewed interest in her career and personal life, including her long-standing feud with Louis Theroux.

In a previous interview with The Times, Ruby Wax disclosed that she would punish her daughters if they mentioned Louis Theroux's name at home, highlighting the depth of her animosity towards him.

The origins of this feud date back to the 1990s, when Ruby Wax was hosting her interview program, 'When Ruby Wax Met...'.

The show featured Ruby Wax engaging in conversations with prominent figures, including OJ Simpson and Madonna, in her characteristic straightforward style.

However, when Louis Theroux launched his television career in 1998 with a notably softer approach to interviewing, Ruby Wax felt threatened, believing that he had usurped her position and livelihood.

Ruby Wax has been quoted as saying that the mere mention of Louis Theroux's name made her feel sick, a statement that reflected the intensity of her feelings towards him.

It wasn't until Ruby Wax appeared on Louis Theroux's 'Grounded' podcast that she was able to confront and clarify her previous remarks, including the comment that his name made her want to 'vomit'.

In a moment of candor, Ruby Wax acknowledged that her comment, although meant in jest, was rooted in her own professional struggles and the perception that Louis Theroux had taken her place in the television landscape.

She expressed that she had 'projected' her career frustrations onto Louis Theroux, and that, in reality, they were both just human beings behind their public personas.

Ruby Wax reflected on her past, recalling a time when she felt invincible and admired, but then faced a sudden decline in her career, which she attributed, in part, to Louis Theroux's rising success.

This period of struggle forced Ruby Wax to re-evaluate her sense of identity, which had been deeply tied to her career and public image, and to confront the feelings of aggression and betrayal that had driven her early success.

Known for her outspoken nature, Ruby Wax has never shied away from controversy, earning her the title of 'diva of the jungle' during her appearance on 'I'm A Celeb'.

Her unapologetic comments and behavior on the show, including a confrontation with a fellow contestant, left a lasting impression on viewers.

In a surprising turn of events, Ruby Wax has since apologized to Louis Theroux, stating that she had misjudged him and that he was, in fact, kind and generous.

Louis Theroux addressed Ruby Wax's comments during the Edinburgh TV Festival, expressing a mix of empathy and flattery, suggesting that the intensity of her feelings towards him was, in a way, a compliment.
