Keith Urban's forthcoming record RipCORD is full of songs he's been recording for going on 15 months. And one of those songs features a well-known rapper: Pitbull.

According to Rolling Stone, Pitbull contributes a rap verse -- the first time that one of Urban's songs has featured a rap -- to "Sun Don't Let Me Down," one of RipCORD's tunes. The country star says that the rapper "brings a mischievous, sexy swagger to it, in a very different way."

"Sun Don't Let Me Down" also features Nile Rogers, who plays guitar on the track, while Urban plays the banjo. They worked together to create something that was a unique product of the two of them.

"Nile does his thing, and I do what I do," Urban says, "but I don't want either of those things — I want what we do."

Fans of Urban's wife, actress Nicole Kidman, will be happy to know that the song's lyrics reference her, at the end of the first verse.

"She's in a movie called To Die For, and in one scene, she's dancing in front of the headlights," Urban explains. "So the lyric goes: 'There in the headlights, dancing like she's in a movie scene. To die for, and she's killing me.'"

"Sun Don't Let Me Down" was produced by Mike Busbee. Other songs that Urban mentions include "Blue Ain’t Your Color" and "Boy Gets a Truck;" Rolling Stone describes them as a “a waltz-like ballad” and “a U2-style anthem," respectively.

RipCORD is scheduled for release on May 6. The album's third single -- following “John Cougar, John Deere, John 3:16″ and “Break on Me,” both of which have hit No. 1 -- is set to debut on Tuesday (March 29).

RipCORD is almost done — and it’s been an exhilarating journey,” Urban reflects. “Getting to work with so many new musicians and writers and co-producers has been a divine experience for me — and I can’t wait for everyone to hear it!”

Urban tells Rolling Stone that this album has been a lot of work, requiring more time in the studio than ever before.

"This is way more than I've ever cut before," he says. "It was a lot of searching, a lot of experimenting, and when you get to work with as many people as I did, you end up with a lot of stuff."

On June 2, Urban will kick off his RipCORD World Tour 2016, featuring Brett Eldredge and Maren Morris.

“I’m seriously champing at the bit to kick off this tour,” Urban admits. “We’ll be playing a lot of new music from RipCORD, all new production, new cities where we’ve never played … and Brett Eldredge and Maren Morris? It’s gonna be potent and unbridled!!!”
