The pop singer, 31, was confirmed among the lineup for the ITV1 reality show earlier today, and declared that she isn't currently romantically attached.
Roberts said: "British men are very charming and if the man of my dreams is in the jungle, then let it be! I am 100% single."
Male contestants taking part in this year's show include Made in Chelsea star Hugo Taylor and boxer David Haye.
Speaking about fears and phobias, the American said: "I don't like enclosed situations either and if I see a bug or rodent, my initial reaction is to run the other way.
"I 100% love my bed. I love my products too. I know I am going to be stripped down and I won't have those luxuries in the jungle - and so hopefully I will learn a lot about myself."
She also claimed that she would avoid boredom in the jungle by doing lots of yoga.
I'm a Celebrity starts on Sunday, November 11 at 9pm on ITV1.
