Mariah Carey returned to the stage for a sold-out show just three weeks after her mother Patricia and sister Alison died on the same day last month.

The 55-year-old icon, who recently said she was returning to work after ‘a couple of rough weeks,’ radiated positivity as she performed her greatest hits at Allianz Parque in São Paulo, Brazil.

Dressed in a striking red gown with a daring thigh-high slit, the legendary chanteuse glided effortlessly across the stage.

She wore her sandy blonde hair long and loose, embracing her natural beauty with minimal makeup, allowing her radiant presence to shine.

The electrifying performance followed Mariah’s announcement on August 27, confirming the series of family tragedies she had endured.

‘My heart is broken that I’ve lost my mother this past weekend. Sadly, in a tragic turn of events, my sister lost her life on the same day,’ she told People.

Alison was 63 when she died while Patricia was 87, according to the outlet, which noted their respective causes of death or the date of the deaths were not immediately clear.

Mariah said she felt ‘blessed’ she was able to ‘spend the last week’ with her mother prior to her passing.

She added, ‘I appreciate everyone’s love and support and respect for my privacy during this impossible time.’

David Baker, a patient advocate told People Alison ‘had a tough life’ ahead of her death at a home in New York.

Baker added, ‘We saw it coming, but it’s still a shock. She got ill fairly quickly and a month later, she’s gone.’

Mariah had complicated relationships with her mother and sister prior to their deaths last month.

Alison was the older sister to Mariah, and the middle child of the late Patricia and opera singer Alfred Carey (who died at 72 in 2002). The former couple, also parents to son Morgan Carey, 64, had been wed from 1960-1973, splitting when Mariah was three-years-old.

Mariah said in her 2020 memoir The Meaning of Mariah Carey that her mother had caused her ‘so much pain and confusion’ and that ‘for [her] sanity and peace of mind, [her] therapist encouraged [her] to literally rename and reframe [her] family.

She said, ‘My mother became Pat to me, Morgan my ex-brother and Alison my ex-sister … I had to stop expecting them to one day miraculously become the mommy, big brother and big sister I fantasized about.’

Mariah said that after extensive therapy, she decided to cease contact with both Alison and Morgan.

Mariah added: ‘I had to stop making myself available to be hurt by them. It has been helpful. I have no doubt it is emotionally and physically safer for me not to have any contact with my ex-brother and ex-sister.’

In the book, Mariah claimed that Alison tried to get her to use drugs and had ‘inflicted [her] with third-degree burns’ when she was a pre-teen, impacting her lifelong development.

‘When I was 12 years old, my sister drugged me with Valium, offered me a pinky nail full of cocaine … and tried to sell me out to a pimp,’ Mariah said. ‘Something in me was arrested by all that trauma. That is why I often say, “I’m eternally 12.” I am still struggling through that time.’

In a September 2020 interview with Oprah Winfrey, Mariah described Alison as ‘troubled and traumatized’ amid their upbringing.

The Someday singer recalled: ‘We don’t even really know each other, and that’s the thing. We didn’t grow up together, but we did. Like, they were on their journeys, by the time I got into the world, they had already been damaged, in my opinion.

‘But again, I wasn’t there. I was dropped into this world and I literally felt like an outsider amongst my own family.’

A source told the New York Post in June 2005 that Alison had ‘been in rehab at least 10 times – many times financed by Mariah.’

While ‘Mariah isn’t one to give up on people,’ she was ‘having to learn that you can’t help someone who doesn’t want to be helped,’ an insider said in the report. One source told the outlet that ‘Mariah, especially, wanted a reconciliation’ with her older sister in 2002 after their father’s death.

‘She thought it was important to try and have something good come out of an awful situation,’ an insider told the outlet.

Following their father’s passing, Alison inherited $1 million, but was not financially prudent with the money.

‘When she got the money, she would spend a week and a half living at the St. Regis, racking up $15,000 tabs,’ a family insider told the outlet. ‘It was very painful for the entire family to see her burn through what Alfred had worked his whole life for. He had wanted Alison to be taken care of.’

Alison returned to prostitution ‘around the time the money ran out,’ a source told the outlet.

In March of 2016, Alison filmed a video published by Dailymail.com in which she appealed to her famed sibling for financial assistance after the 2015 attack that left her injured. She said, ‘Mariah, I love you. I desperately need your help. Please don’t abandon me like this.’
