Yeap she has lip injections. Because when someone has lip injections and when they do the kissing pout with their lips, their lips does not have that many folds and lines formed on their lips. And the lips also widen when doing the kissing pout. And there are pics of Ariana doing those pose with her lips which makes it pretty obvious she has lip injections. It is clearly not over lining of the lips. I know Ariana fans will become defensive when it comes to people thinking Ariana has alterations but I mean come on, so what if she has. It's okay. Don't need to be so defensive over it.....
