Who is Aimee Osbourne and why is she estranged from sister Kelly? Inside the pair's frosty relationship

The wild Osbourne clan crashed onto screens in 2002, lifting the lid on their wild antics and their foul language.

While Black Sabbath star, Ozzy, 75, was already known, it saw his wife and music manager wife, 71, and their two children, Kelly, 39, and Jack, 38, skyrocket to stardom.

But despite The Osbournes giving fans a peek into their lives over the course of a whopping 52 episodes - we didn't meet the whole family.

For those less familiar with the brood, Kelly and Jack also have a sister named Aimee, who has largely shied away from the limelight.

But even behind the scenes, the 40-year-old and her sister Kelly do not have a sisterly bond. Now MailOnline takes a look at their frosty relationship.

When MTV began filming The Osbournes, Aimee decided to leave the family home at the tender age of 16 (left to right: Jack, Ozzy, Kelly, Sharon and Aimee Osbourne in 2011)

Who is Aimee Osbourne? 

Aimee has kept her life largely private. Similarly to her musical father, the eldest Osbourne sibling is the lead singer of pop band ARO 

Aimee Osbourne was welcomed into the world in London on September 2, 1983.

She was largely raised in California until the age of 16, however she eventually moved out of the family home as filming for The Osbournes kicked off. 

Labelled the 'hermit' and 'enigmatic' Osbourne sibling, Aimee has kept her private life largely under wraps.

The 40-year-old pursued a career in music, similarly to her rocker father.

In 2003, she featured in the MTV musical adaption of Wuthering Heights. 

Presently she is the lead singer for pop band ARO, whose first single Raining Gold was released in 2015. 

The eldest Osbourne sibling also had a close brush with death, surviving a deadly fire in a Hollywood recording studio in May 2022, according to People.

Both she and her producer managed to walk away with their lives, but unfortunately one person did not.

Sharon shared on Instagram: 'It is utterly heartbreaking that someone lost their life today in this fire & we are sending our prayers to this person & their family. 

'What happened today was beyond horrific.'

Why are the Osbourne sisters not close? 

Kelly Osbourne confirmed in 2021 that the two no longer talk following a clash in personalities. 

The reality TV personality, who appeared on the Dax Shepard podcast - Armchair Expert - revealed she and her older sister had been estranged for a long time.

On the podcast episode, which aired on May 3, 2021, Kelly said the pair were unable to get on the same page.

'We don't talk,' Kelly, then 36, told Shepard. 'We're just really different. She doesn't understand me and I don't understand her.'

Back in 2015 Aimee shared with The Independent that her and Kelly were not on close terms.

'I wouldn't say there is an ease between us, but there is an acceptance,' she said. 'Do we socialize? No.' 

However, Aimee and Jack's bond is staggeringly different, with the pair both running production company Osbourne Media together.

The siblings are also in the process of co-producing a biopic about their parents, according to Variety.

Aimee, who is the eldest child of Sharon and Ozzy decided against featuring in their reality TV show, moving out of the family home at 16.

She said that she would have liked to stay at home 'a little longer', but as the MTV crew moved in the then teenager moved out.  

Reflecting on her decision to not appear on the show she added: 'Back then, I still felt I was trying to figure out who I was in the chaos of family life, so why on earth would I want that portrayed on television? 

'I wanted to protect myself, my parents, my siblings, too. They were very young, very impressionable.'

Sharon said on the Talk in 2018: 'She felt too that she didn't want to grow up on camera. She hated the idea — it was appalling to her.

'And so she left at 16 and I regret every day that she did. It broke my heart when she moved.'
