Jessie J has claimed that some popstars are "mean" and "miserable" behind the scenes because they party too hard.
The singer explained that she quit drinking alcohol a year ago and avoids parties in order to remain professional and focused on her career.
"I like my life to be pure and clean and organized, and I like to have had eight hours' sleep a night," she told The Observer.
"I honestly don't think I'd be as successful if I was a party animal. Because I don't think my personality would be as focused and open as it is.
"I won't mention no names, but I've met artists who are so 'on it' when they're on camera, or on stage, so the audience and the media thinks that they're like that, and then you see them come off stage, and they're mean, they're miserable and they're late.
"I want everybody to think I'm a hard worker as an aunt, a sister, a friend, a daughter, a niece, everything. I want to be great at every role, because every role in my life is as important as being Jessie J."
Who is Jessie talking about? (do you think she's shading rihanna?) source
I don't think Jessie J has ever met Rihanna. I know she was always talking about how she would love to write songs for her and is her dream collaboration. She's probably talking about a UK artist like Lily Allen or something.
