The 'On A Mission' star posed for FHM's May issue, but later found out that the publication had enhanced several of the images.
"I think I'm happy with about three of those shots, and I would very happily use some of them as the front cover for my record," the 18-year-old told WENN.
"But there are some in there that I look at them and I don't see how they related to me in any way. They've given me bigger boobs than I have anyway. So, I guess you get like a free boob job or something."
She continued: "I look at them and I laugh at them, because I know that they're not very representative of me, and who I am as a person, and what my music's about. I thought Pink's done it, Beyoncé's done it, all these people have done it, and I'm like, 'You only live once, why not give it a shot?'
"Would I do it again? I don't think so. I guess you learn not to get caught up in the same stuff, you learn for next time. I don't regret it, but I wouldn't do it again."
