Shakira reckons she learned her mind-boggling moves from flipping a coin with her stomach muscles.
The Colombian stunner said: "You just have to roll that belly... I used to practice by trying to flip a coin.
"But don't try that after eating."
During her Live Lounge performance on Fearne Cotton's Radio1 show, the singer spoke about her eye-popping flexibility in the She Wolf video, reports The Sun.
Shakira said: "It's one of those moves I just thought of in the studio when we were shooting the video and it felt right.
"She Wolf is the woman of our time... the woman who know what she wants and is free of prejudice and pre-conceived notions.
"She defends her deepest desires with teeth and claws like a wild animal."
Shakira added: "I assure you every muscle ached after that video."
