Connie Francis, who was at one time the world's biggest-selling female artist, has died at the age of 87.
The musician, whose hits included Stupid Cupid and Who's Sorry Now, had recently enjoyed a resurgence after her 1962 song Pretty Little Baby went viral on TikTok.
Francis had recently been treated for pelvic pain caused by a fracture. During her stay in hospital, she was diagnosed with pneumonia and died on Wednesday night, the president of her record label, Ron Roberts, told BBC News.
Roberts had previously announced the star’s death on Facebook, “with a heavy heart and extreme sadness.”
The star's death comes just months after Pretty Little Baby became a trending song on TikTok.
Millions of people, including Kim Kardashian and Kylie Jenner, lip-synced to the easy listening ballad, while showing off their children and pets, or making displays of affection.
One video, by social media influencers Brooke Monk and Sam Dezz, was watched more than 158 million times.
ABBA singer Agnetha Fältskog also posted the song, saying that Francis had long been her favourite singer. And the actress Gracie Lawrence, who is currently playing Francis in the Broadway musical Just in Time, also shared a video of herself singing the track, while dressed in character.
Speaking last month, Francis said she had been surprised by the sudden success of a track that had originally been a b-side.
"To tell you the truth, I didn't even remember the song!" she told People magazine.
"I had to listen to it to remember. To think that a song I recorded 63 years ago is touching the hearts of millions of people is truly awesome. It is an amazing feeling."
