Columbian star Shakira

Colombian singer Shakira has revealed that she asked permission from her footballer partner Gerard Piqué before filming a raunchy music video with pop star Rihanna.

Shakira and Bajan bombshell Rihanna turned up the heat in their duet, Can't Remember to Forget You.

In the four-minute visual, directed by Joseph Kahn, Shakira and What Now singer Rihanna are seen rubbing each other and twerking in a series of skimpy outfits.

In an interview with US radio presenter Ryan Seacrest, 36-year-old Shakira talked about asking Piqué's permission to do the video, which received rave reviews but was blasted for "promoting lesbianism".

"I told him. I asked him if he agreed with everything and he agreed. I wanted to make sure because he's super jealous. He's a man. He's territorial. He wants to know everything is under control," she said.

Shakira admitted that she knew the video was going to be a little controversial. She said: "I knew people would be interested especially because Rihanna is so big, but these numbers are unbelievable."

In an interview with US Glamour magazine, the Hips Don't Lie hitmaker confessed she had a girl crush on Rihanna.

"Working with her was utopia," said Shakira. "She's the sexiest woman on the planet. And at the end of the day, we're both just basically Caribbean girls."

"The chemistry was so good and so real. She taught me dance moves. She was a sweet teacher."
