The Vamps star Bradley Simpson says former tour buddy Sabrina Carpenter's success is "so well deserved".
The 'Espresso' hitmaker, 25, was the opening act on the boy band's 2017 tour, and Bradley - who has recently embarked on his solo career - has heaped praise on the pop superstar and her breakthrough album 'Short n' Sweet', hailing her "such an amazing, hard-working artist".
