Mariah Carey is planning to pull double duty at her next video shoot.

The singer wants to film two clips at the same time when she begins shooting on Thursday, much like she did for the dynamic duo "It's Like That" and "We Belong Together." This time, Carey is set to lens a clip for her next single, "Shake It Off," along with its follow-up, "Say Somethin'."

"We're making two videos," she said. "I actually just got the treatment. We came up with some cool concepts."

What those concepts actually are, Carey wouldn't reveal -- because it's "really technical."

"It's a new approach that I would have to let [the director] explain," she said. "It's new territory."

Don't look for a storyline that ties the two videos together, as found in the last pair, when she left Eric Roberts at the altar in "We Belong Together" to run off with Wentworth Miller -- who came into her life in "It's Like That." (see [article id="1499772"]"Mariah Carey: Free At Last?"[/article]). While Carey is rooting for a cohesive narrative storyline, she thinks the clips might end up having a "slight" link that comes across only on a subliminal level. Brett Ratner was originally slated to return to direct the videos, but Carey has since selected another director, Jake Nava -- at least for "Shake It Off."

"I think people can relate to [the song] no matter what you have to shake out -- be it a bad day, a guy, a girl, whatever it is," Carey said. "It's one of those fun songs, where we're not taking ourselves too seriously, but it does say something, and it is real."

Carey worked on "Shake It Off" with Jermaine Dupri, but only after she rejected "Say Somethin' " (which she recorded with Pharrell Williams and Snoop Dogg) as the first single from The Emancipation of Mimi.

"L.A. Reid was totally into 'Say Somethin' ' as the first single," she said. "And I was like, 'It's great, but I don't know.' ... It's very Pharrell. He very much goes in that jazzy kind of direction, which is great. I could go there with him, but it's just not where I would naturally go.

"L.A. was like, 'You and Jermaine make magic,' " Carey continued. " 'Why don't you go work with Jermaine?' And I was like, 'Well, I love Jermaine. Is he free?' "

Dupri offered to start working with the singer the next day. "So I went down there and did two records with him in two days," Carey revealed.

The easygoing nature of their recording sessions was an exact match for what Carey wanted for her Emancipation proclamation, she said.

"To me, the spirit is very kind of free and fun and lighthearted," she explained. "It wasn't like I consciously said, 'I'm going to have a good time.' But I mean, it was just where I'm at in my life, naturally."
