Ariana Grande revealed that Justin Bieber has been texting her for some time and that his messages to her can get flirty, possibly dating back to when he was still in a relationship with Selena Gomez.

The Baby I singer is currently touring with Bieber and in an old interview with M Magazine she opened up about the moment they first exchanged text messages, reported by Hollywood Life.

"Justin's the most famous contact I have in my phone," the 20-year-old said. "I felt so cool when he started texting me. I didn't believe it was him at first. He wrote, 'What's up cutie?' I dropped my phone and thought, 'That did not just happen,' "

Aside from text messaging, Bieber, 19, also complimented Grande on her music.

"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," she said. "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."

Grande's Die In Your Arms cover was released in 2012 while Bieber was still dating Selena Gomez, 21. The former couple broke up reportedly toward the end of that year, but the Come & Get It singer still has a crush on Bieber, according to a source.

"Selena is still not over Justin, not even close," the insider said. "From what all her friends are saying, she's still majorly hung up on Justin."

Until August Grande was in a 10-month relationship with Jai Brooks, an Australian star famous for being a member of the YouTube comedy group The Janoskians. The Disney star is now dating The Wanted's Nathan Sykes, though in a recent interview with Ryan Seacrest she would only admit "he's awesome." When Seacrest noted that Sykes is a cool guy, she added, "I like him too."
