The surviving twin of a 96-year-old woman who died after being struck down by coronavirus is "in shock", family members say.
Adored Doris Hobday, 96, one half of the Tipton Twins, passed away earlier this month in hospital after a two week battle with the virus.
Tragically, she died just two days before her vaccination letter arrived.
Her twin, Lilian Cox, who also contracted the virus, was left devastated after she was discharged from hospital this week and told her twin had died.
“We explained this week that Doris had died and said 'nan, we couldn't tell you before because you were so weak',” Lilian's granddaughter Kerry Clarke, told The Mirror.
“It's heartbreaking, she's in shock. She can't believe it because she's okay and Doris didn't make it.
"It's heartbreaking, she keeps looking up at the sky.”
Kerry, 35, from Hagley in the West Midlands, says she now wants to appeal to the public to have a blood finger oximeter in their home.
“My aunt and nan thought they were fine so they didn't want to go to hospital at first,” she said.
“My aunt Doris had never been admitted to hospital before.
“Nan had a little cough and Doris had no cough at all but a high temperature."
When she was tested she told them that her sister had a little cough and needed checking too.
“But what we didn't know is that Doris's oxygen levels were deteriorating," Kerry said.
“These little oximeters you can buy are crucial because the elderly will feel they are fine but the truth is they could be dying.
“We wished we knew about them sooner.
“If Doris had gone into hospital a week before she might have had a chance.
“What's even sadder is that Aunt Doris was weeks away from being safe.
“Two days after she passed, she had a vaccination letter. It's just horrible.”
Kerry said when the twins discovered they had Covid they were “shocked” at first, as they had no idea how they caught it.
“They hadn't been out for months and followed all the rules,” she said.
“They didn't even spend time with their family on Christmas Day.”
A family statement said: “Both were determined to live until 100, they had so much to live for...it's just so cruel that Covid has stopped Doris like this.
“Our thoughts go out to all the families who have experienced a loss through Covid and we urge people to take this seriously.”
The twins shot to fame with a series of hilarious TV interviews and have 35,000 followers on social media.
They caused a stir on This Morning when they told Phil Schofield they had forgotten to put on underwear.
And they made Piers Morgan blush when they told of their love for him and Jason Statham.
They also revealed the secret to a long life was “plenty of sex”.
Piers told viewers Wednesday morning how they were two of his “favourite guests” and a real “ray of sunshine”.
“What a wonderful lady, who led a wonderful life and kept up that extraordinary personality and enthusiasm and zest for life right until the end,” he said of Doris.
"They brought such cheekiness, such laughter - they were a wonderful duo."
Inseparable Doris and Lilian, lived on the same street most of their lives until they moved next door to each other in warden controlled flats.
Lilian is now being supported by her family and staying with her daughter Vivien.
Her twin will be laid to rest with her husband Raymond of 65 years who was the “love of her life”.
She lost him 11 years ago.
Doris and Raymond, who never had children, worked together in a factory for most of their lives.
They used to spend their spare time riding around in a motorbike and sidecar.
But later in life Raymond went suddenly blind Doris devotedly cared for him.
Lilian has set up a fundraising page in her sister's memory to raise money for Doris's favourite local charity, The Beacon Centre for the blind.
Her funeral is taking place on February 15 and she will be buried alongside her beloved husband.
