I called the phone number through boredom and after a few rings I heard a message that was oddly quite similar to her Britney's real voice. Cool! I didn't have any intentions of bothering her I just wanted to hear it for myself. If she wanted to change her phone number than I think she would have done it a long time ago. Anyway...that was pretty cool.
Britney: Hello?
Me: Hi, is Britney there?
Britney: Hi
Me: Is this Britney?
Britney: yah
Me: What's your last name?
Britney: What do you think it is?
Me: Spears..
[silence]
Then I heard a few clicking sounds and she hung up.
It sounded exactly like her by the way.
We called the number, and she answered. We talked for about five minutes, but we don't know if it was really her. If it was, she sounded pleasant, and she told us to have a happy holiday! =D
