The diminutive singer features on a new track, 'Bang Bang', with the rapper and British singer Jessie J and is full of praise for her collaborators.
She told 'Entertainment Tonight': ''I love [Nicki's] personality. I love Jessie's personality. They're both so full out with feeling. I love them so much.
''Jessie is always singing, which is my favourite thing because so am I, and Nicki is hilarious. I love her. She's so sassy.''
The trio of pop divas will perform for the first time collectively at the MTV Video Music Awards this weekend, marking Jessie's first performance at the bash since 2011.
Jessie had to scale back her performance at the time due to a broken foot and so she can't wait to give it all she's got this year.
She said in a statement: ''When I was the VMA House Artist in 2011 I had a broken foot and I sat on the side stage dreaming about being on that main stage. So when I say that this performance is a dream come true for me, I truly mean it. And to be able to share this moment with superstars like Ariana and Nicki, it's going to be such an amazing night!''
There's already an Oscars buzz surrounding this movie.
