Ariana Grande joined Justin Bieber during his Believe tour on Wednesday and performed some songs from her upcoming debut Yours Truly.

During the performance, Grande sported a short white dress and demonstrated her strong vocals as she hit the stage at the Jacksonville Veterans Memorial Arena in Florida. Grande's set included the un-released tracks Lovin It, You Will Never Know, Tattooed Heart and My Piano. She also performed the album's two already released singles, The Way and Baby I.

The Nickelodeon star released the album's lead single The Way, featuring Mac Miller, in March. The video has garnered over 75 million views on YouTube and the tune also earned her comparisons to Mariah Carey, whom Grande said she admires.

"You know I love just like old R&B. I love the '90s, that whole vibe. I love Mariah Carey, of course, she's the goddess of all vocals," she told MTV in May. "But, yeah, I just wanted to do something old school and soulful and something that I like to sing. And that's what I really clicked with."

The songstress then released Baby I, the album's second single, in July. Following its release, the song quickly rose on the iTunes charts. Her tour mate congratulated her via Twitter.

"I see everyone going crazy over your new song. You can sing! See u on the #BelieveTour. Congrats!," Bieber wrote to her on Twitter.

The 20-year-old also revealed her debut album's release date and cover art via Instagram in late July.

"My debut album Yours Truly will be available for preorder next week & released September 3rd," she wrote along with the colorful photo.
