Shakira's currently the lone woman among the quartet of coaches on "The Voice," and when she takes a break next season that spot will fall to Gwen Stefani. But Stefani better prepare herself. It's a distinction that comes with certain hazards.

When TODAY's Hoda Kotb sat down the season six panelists, the Colombian singer — and one of the men she shares the stage with — revealed that boys will be boys.

"They crack some jokes that, you know, you don't want to be around," Shakira said.

"I tell fart jokes," the newly-blond Adam Levine was quick to add. "Blake just farts."

"You don't want to hear the things that I hear," Shakira warned.

While Stefani will probably have to hear those things, Shakira is certain that both the "Hollaback Girl" singer and her fellow incoming coach, Pharrell Williams, will handle their new gig with ease.

"I think that they will both do a terrific job," she insisted. "Pharrell is unafraid, and he's always trying things. And Gwen is so smart and cool."

And with an eye to Levine and his on-screen banter buddy Blake Shelton, Shakira added, "I'm sure she will have the hide to deal with these guys."

Luckily for Stefani, Levine and Shelton often keep each other busy — as they did when the topic of Levine's platinum tresses came up.

"There are a lot of more important things to care about," the Maroon 5 frontman said.

But Shelton disagreed.

"It's big-time stuff," he said. "You're the sexiest man in America. … And now, you're the sexiest woman in America. It's a big deal."

Those might be fighting words, but no worries. After Shelton's stunt last week, in which he tweeted Levine's personal phone number, Levine already owes him one.

"My lips are sealed, you guys," the rocker vowed when asked about how he plans to exact his revenge. "I would never reveal my tactics as far as taking him down."

As for Shelton, he thinks Levine's already had his laugh. "Yeah, I think what he did with his hair is a joke that he's playing on me, 'cause it's like, 'Ha ha! I can't believe you thought I would ever do that.'"

Boys will definitely continue to be boys on "The Voice."

"The Voice" airs Mondays and Tuesdays at 8 p.m. on NBC.
