How do i remove someone as my Girlfriend with Siri?

Ok here it goes....I asked Siri to call my Girlfriend...siri responds, i dont know who your girlfriend is...who is your girlfriend? I say Jennifer...Bam! Siri says ok...now me and my girlfriend broke up...and i cant figure out how to remove Jennifer as my girlfriend...poor Siri still thinks we are together and ive asked Siri to Remove Jennifer as mygirlfriend, and Siri says its not allowed to do this. I Immediately looked in my contacts for some sort of string in the contact info for Jennifer that makes her my girlfriend, and there is nothing there. Im quite confused, and i dont need siri calling my ex when i have a new girlfriend.. HELP!!!!!
