'Problem' songstress Ariana Grande has taken to her official Twitter page to ask her followers to be nice to each other online. 

Writing on the social networking site earlier today (May 11), she explained that it makes her feel sad to see fans bickering amongst themselves and she wants everyone to get along:

"I hate coming online to see y'all fighting. You're all my babes and I love u with all my heart. Smile, there's much to celebrate thanks to U."

Grande, meanwhile, recently confirmed that she has been in the studio working on a collaboration with Canadian sensation Justin Bieber and it's on a track that he wrote himself: "Im excited about it… I’m just very excited. Justin wrote it and he brought the idea to me."

She added: "And I was really excited to hear it and I’m excited to work with him. I’ve wanted to work with him for a while. And I know it’s something our fan have been begging for for years now.”
