Miley Cyrus’ mother Tish Cyrus revealed her belief in a head-scratching conspiracy theory during a recent chat with her daughter Brandi.

The mother-daughter team appeared on Harry Jowsey’s podcast, Boyfriend Material, where Tish shared an unconventional theory about Los Angeles’ secret landscape, which somehow led to a side note about Will Smith.

‘Tell him about the LA tunnels,’ Brandi instructed her mother in a tone that suggested she was sick of hearing about them.

Miley became involved in the conspiracy talk when Tish—whose husband, Dominic Purcell, recently revealed a bold new appearance—started to say, ‘Miley told me—,’ only for Harry to interrupt her.

‘That’s not real,’ he interjected at the idea of an underground tunnel system beneath LA, but before Tish could explain her thoughts, Brandi mentioned that her mother was already ‘convinced’ about it.

‘I’ve heard the LA tunnels are real,’ Tish, 58, said cautiously.

The mother–daughter duo were guests on Harry Jowsey’s podcast Boyfriend Material when Tish began to spout off an unorthodox belief about the secret geography of Los Angeles that managed to include a digression about Will Smith (pictured July 13 in Wolfsburg, Germany)

‘I heard Will Smith has a whole underground bunker in LA,’ she continued.

Brandi, who initially sounded skeptical, was suddenly won over by the Fresh Prince star’s connection to the conspiracy theory.

‘I believe it,’ she added to back up her mother. 

Tish added that Smith would be protected in the future ‘when s*** goes down and there’s all kinds of —’ before the clip censored what she was saying with ‘Sorry, secret’ stamped over her mouth.

Her mysterious prediction for the future was of interest to Harry, who raised his eyebrows and added, ‘Oh really?’

He suggested that Tish’s connection to celebrities via her children might help to put her conspiracy beliefs to bed once and for all.

‘I feel like you guys could probably just figure it out because you’re closer to them than the rest of us,’ he said with a laugh.

Miley’s mother, who was dressed in a black tonal pinstriped suit jacket with skinny black jeans, shared her fears that there was ‘all kinds of stuff that’s going to happen,’ possibly in the event of some kind of societal upheaval.

‘I’ve heard the LA tunnels are real,’ Tish said cautiously while both Brandi and Harry disagreed with her

Brandi interjected to taunt her mother, saying she ‘loves a conspiracy.’

‘But I don’t think they’re conspiracies! I think they’re true,’ Tish shot back, while Brandi reminded her that ‘all conspiracy theorists’ think that their pet beliefs are true.

Tish and her daughter squared off as the matriarch tried to suggest that the term ‘conspiracy theory’ was created by the ‘government’ to dismiss facts as the ravings of cranks.

‘That’s what they all say,’ Brandi taunted her mother while Harry burst into laughter. 

Tish’s podcast appearance with her oldest daughter comes after she managed to bury the hatchet with her younger daughter Noah Cyrus.

The two had been rumored to be feuding over Tish’s 2023 marriage to the actor Dominic Purcell, 55, whom 25-year-old Noah had previously dated. 

Fans speculated that the feud was the reason Noah and her brother Braison ended up skipping Tish’s nuptials, which were put on at Miley’s home in LA. 

However, an insider claimed to Entertainment Tonight that it was Tish who didn’t invite Noah and Braison, and they accused her of blocking them on Instagram after she began a relationship with Dominic.

The two were reportedly feuding after over Tish marrying Dominic Purcell, 55, whom Noah, 25, had previously dated. But the two had a thaw earlier this year and later buried the hatchet on Tish and Brandi’s podcast 

But a potential thaw appeared to be in the works when Noah was seen spending time with her mother in July 2024.

By April of this year they had buried the hatch with Noah’s appearance in a TikTok video, followed by her joining her mother and Brandi on their Sorry We’re Cyrus podcast. 

Tish and Noah steered clear of any talk of a feud during their chat, but Tish did reveal how they grew closer again.

She said that her daughter simply moving closer to her meant they were able to take walks together again, which helped them bond.
