Justin Bieber, Ariana Grande Dating Rumors [PHOTO]: 'Baby I' Songstress Praises New Song 'Heartbreaker' Amidst Text Message Flirting Claims

Though Ariana Grande insists that Justin Bieber is simply a close friend, there are still some dating rumors about the pop stars. Thanks to an interview earlier this year regarding some flirting text messages suddenly popping up once again, the "Baby I" singer has to deal with this gossip. The fact that Grande is touring with Justin doesn't calm the rumors either.

"It's amazing - so much fun and Justin is so nice and his fans are so amazing," the 20-year-old singer said about performing on the "Believe" tour. "I felt so at home. It was an amazing, incredible experience."

Ariana also gushed about hearing Justin's anticipated new single, "Heartbreaker."

"Oh my God, I did hear 'Heartbreaker' and it's really good," she said. "That's the one thing I do get to hear, new music, and it's really good! I can't say anything about it but his fans are going to be really happy!"

Earlier this year, Ariana revealed that Justin had sent her some flirty text messages at one point.

"Justin's the most famous contact I have in my phone," she said in the interview with M Magazine. "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.'"

This interview started all of the dating gossip, but Grande has also been linked to The Wanted's Nathan Sykes as well. Grande's recent success and fame are clearly something she needs to get used to.

When asked about her 2013 Video Music Awards performance, Ariana said: "I was about to pee my pants! But as soon as it started it was really fun. It was a great experience!"

"It's a massive compliment - it's an honor," she said of being compared to Mariah Carey. "She's the queen vocalist so it's the biggest compliment and it's very exciting for me. But I'm excited for people to hear my album, my sound."

Ariana's album, "Yours Truly" is currently number one on Billboard 200.
