The 20-year-old star has previously been linked to Joe Jonas and Taylor Lautner and said you just never know what's around the corner.
Speaking to Parade magazine, she said: 'Things change so quickly. I have no idea who's going to be a recurring character and who's just a guest star for one episode. Love is fascinating.
'Wishing for it, pining for it, and the anger that comes when you lose it. I used to think that I could figure out some pattern to love, like if you don't text a guy back for a half hour, he'll like you more.
'But there is no pattern. Absolutely nothing is predictable in love or in life.'
