Sabrina Carpenter and Paul McCartney lead tributes to Dolly Parton.

Sabrina, 27, shared a gallery of photos of herself with Dolly, who died at the age of 80 on 25 August, accompanied by a heartfelt caption that described Dolly as "an angel." "oh dolly, the only thing i could say after we first met was 'she really is an angel walking the earth' and 'we look like we could be sisters!'" The singer, who featured Dolly in a duet of the late octogenarian's country hit Jolene on the deluxe version of her album, Short n' Sweet, went on to lament the loss of Dolly's "singular magic."
