Shakira has revealed that working with Rihanna on their duet 'Can't Remember To Forget You' was "Utopia" for her.
The 36-year-old Colombian singer-songwriter, who is set to make a comeback to music after giving birth to her first child, said that the 25-year-old Barbadian recording artist is the "sexiest woman on the planet", the Daily Star reported.
The 'Hips Don't Lie' singer added that their chemistry was so good and so real and credited their Caribbean origins for it.
