The 19-year-old star - who is dating Justin Bieber - is "open" to returning to her studies in future but is currently happy to focus on her career.
She told `The Ralphie Radio Show`: "I`m of course always open to [going to college], but at the moment I`m definitely enjoying where I`m at right now and having a great time touring and focusing on that."
The `Love You Like A Love Song` singer also insisted that recent speculation she is to star in a new prequel to hit TV series `Sex and the City` is not true, though she admitted she would be "honoured" to appear if the show did happen.
Asked about the speculation, she said: "That`s all rumours, it would definitely be an honour but I haven`t been approached
"I am a `Sex and the City` fan, actually my mom is probably more, I wasn`t allowed to watch it when I was younger, so I kind of missed a lot but I saw a couple of episodes."
