According to UK newspaper the Daily Star, the Geordie singer is said to have become “addicted” to the drink when she holidayed in South Africa with pal Derek Hough, 25, over the New Year.
A hotel worker at Mount Nelson Hotel told the newspaper: 'Cheryl told everyone she was addicted to carrot juice as it makes her skin glow and helps her nails stay long and strong. She'd start the day with two glasses, then order up to six glasses by the pool with a tray of smoked salmon.'
The 27-year-old Girls Aloud star is allegedly on a health-kick, which has also seen her cut back on fizzy drinks.
Her spokesperson denied that she is on a special diet.
