ET caught up with Mariah Carey in Paris, where she filled us in on how she's planning a wedding while on a world tour.

"I tried my dress last night," the pop diva told us backstage at one of her shows on the Sweet Sweet Fantasy Tour last week. "It looks good. They came and brought it … I can't say the people. I can't say their names. The fabulous designer house that's amazing."

Carey and her Australian billionaire businessman fiancé, James Packer, became engaged in January. Their nuptials will mark the third marriage for both of them. Packer has three children from his marriage to Australian model and singer Erica Baxter, while Carey has four-year-old twins Monroe and Moroccan from her marriage to Nick Cannon. Since both have walked down the aisle before, Carey told ET that they're being "normal" about the wedding.

"I'm just going with whatever I like," Carey shared.

But there's nothing normal about the singer's epic 35-carat engagement ring, which the world got a glimpse of in January, or their jet-setting lives.

In Paris, Packer flew in five days before Carey's April 21 show to surprise her, and the twins, Roc and Roe, have also been traveling with her.

"They love it. They want to go on the airplane," Carey said of bringing her kids on the road with her. "If we stay somewhere too long, they don't really like it. They're travelers."

During her tour, cameras are also filming the E! eight-part docuseries, Mariah's World, which has been shooting since at least February and will follow the superstar's tours of Europe and South Africa.
