"I'd love to do a worldwide tour," the rising star told Billboard last week.

Ariana Grande is enjoying a landmark week, as her debut album, "Yours Truly," debuted at No. 1 on the Billboard 200 chart with 138,000 copies sold in its first frame, according to Nielsen SoundScan. Before "Yours Truly" officially made it to the top of the chart, Billboard caught up with the 20-year-old Nickelodeon star for a chat about her whirlwind year, future touring plans and recently released "Baby I" music video.

After her breezy music video for "The Way," featuring Mac Miller, helped her become a star upon its release last March, Grande wanted to take things back to the decade in which she was born for the "Baby I" visual. "It's like a 90's, throwback-type vibe," says Grande of the video, which has earned 4.6 million views since its release last Friday. "When I said 'I want it to look like this,' I said like a TLC, Fresh Prince type vibe. I was like, 'Let's just get really silly, 90's amazing outfits, and just go out and dance around and have fun."

Before Grande performed on national platforms like "The Today Show" and "Late Night with Jimmy Fallon," the singer embarked on her first headlining tour, a short trek dubbed the Listening Sessions, in August. Although her next tour has yet to be announced -- and despite a brief setback due to a hemorrhaged vocal cord, after which she is now "totally fine" -- Grande says that she wants her live show to reach as many fans as possible.

"I'd love to do a worldwide tour," says Grande, "and go sing for my fans in other countries, and meet them… I want to get overseas and meet everybody over there, and perform for them. I think that'd be a great experience."
