On Thursday fans of both Rihanna, 25, and the Columbian singer, Shakira, were no doubt further excited when the cover art for their hotly anticipated collaboration surfaced.
Shakira, 36, is seen shooting a smouldering pose at the camera, as she wears a cut-out black body accessorised with a black and gold medallion and framed by her ever-present tumble of blonde locks.
While Rihanna is seen reclining seductively in her lap wearing a high-cut strapless black bodysuit and draped in costume jewels in the stunning artwork for the single which is released on iTunes January 14th.
Shakira, who grew up in Barranquilla, Colombia, said that she had found a lot in common with Rihanna after getting to know her during recording.
She said: "Working with her was utopia. 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."
Shakira famously worked with lookalike singer Beyonce on song Beautiful Liar, and the pair were identically styled in the accompanying music video.
And with Rihanna known for her racy music clips, fans will no doubt be treated to something memorable when the video is released.
The Barbados beauty shared a photo teasing the release of the new song due to be released on Monday earlier this week on Instagram.
"One. Week. Countdown," RiRi wrote with a photo. The single, which will officially release on January 13, was first mooted by chart-topping singer Pitbull.
Pitbull first teased fans with the idea that Shakira and Rihanna had recorded a duet for the Latina pop singer's forthcoming album.
He shared he originally wanted Rihanna to record the hook on his recent single, Timber, featuring Ke$ha.
"That is an ironic situation there. The person we were looking at first to work on that record was actually Rihanna, and Rihanna had something she had to do with Shakira, so she wasn't able to work on our record," he shared in a radio interview last month.
