And it begins!

Fresh from announcing the release of her big comeback single with Rihanna, a tousled Shakira serves as Glamour mag's February cover girl.

Speaking of Riri, she's apparently a utopian model of physical perfection-- at least, that's what Shakira says.

“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.”

Well, we can't argue with that.

Besides plugging her new single, Shakira's also promoting her return to The Voice. The Colombian beauty opened up to Glamour on what it's like to work on the show, and the challenges she faces being the only female mentor.

“Dealing with boys at work and being the only girl can be challenging. I have my insecurities, but I’ve learned I have to be a good sport. I have to be able to take certain jokes and not take them personally. There are jokes made almost every second of the day. I had to develop a tough hide. You know, the music industry is dominated by guys. I work with men 98 percent of the time—producers, arrangers, musicians, engineers.”

Shakira & Rihanna's "Can't Remember To Forget You" drops on January 13, and season six of The Voice premieres February 24.
