Ariana Grande, a Twitter and Tumblr queen, is getting text messages from Justin Bieber in 2013. Nathan Sykes rumored girlfriend and "The Way" singer said that Biebs flirts a lot.

According to Hollywood Life, Grande, 20, told M Magazine that Bieber, 19, has her phone number, and sent her more-than-friendly texts in an old, but recently resurfaced interview.

"Justin's [Bieber] the most famous contact I have in my phone," Grande said to M. "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 redheaded singer also revealed that Selena Gomez' ex also complimented her.

"I did a cover of 'Die in Your Arms' and Justin tweeted it," Grande continued, "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."

She also told M about how she would love to work with Bieber one day, and that she thinks that Austin Mahone's rumored rival is adorable and amazing. 

It appears now that the two singers are really friends, who happen to like each other as entertainers.

But there's been speculation of a romance between the friends lately after an intimate photo of them went viral. For our story on Grande and Bieber's flirty photo, click HERE.
