Ariana Grande has revealed that Justin Bieber sent her flirty text messages.

The pair have toured together and they were recently pictured on Twitter getting close as Bieber landed a kiss on her cheek.

In a new interview with M magazine, Grande admitted that the 'Believe' man once flirted with her via text messaging, saying:

"Justin’s the most famous contact I have in my phone. I felt so cool when he texted me. I didn’t believe it was him at first. He wrote, ‘What’s up cutie?’ and I dropped my phone and thought, ‘That did not just happen'."

The rising star added: "I did a cover of ‘Die In Your Arms’ and Justin tweeted it and said he liked it and that meant the world to me. The fact that he did that means that he thinks I have some credibility as an artist. I’d love to work with him one day, I think he’s adorable and amazing."
