I got this from the official Eminem forum
"The rumor is her name is Antonia and she is from the UK...I guess they are pretty tight...If it is bullshit I'm sure we will hear about it...We will see..."
I found a formspring page for Hailie Scott http://www.formspring.me/HailieScott there are several pages of her. She says her dad has a GF and her mom does not have a boyfriend. She also said they will becoming public soon. She says she is aloud to talk about her dad's GF but certain things she would never discuss on facebook or twitter. She says his GF's name is Antonia from the UK and they will be going public soon. She says she goes to a public school, I thought she went to a private school? She says she can't post pictures of her and her dad on twitter or facebook because they leak to easy. There is also someone on formspring. that asked Hailie "Why does your dad love me so much?" claiming to be Antonia. Hailies reply was "HaHaHa He said he will tell you Saturday." http://www.formspring.me/antoniauk. She also says her dad is going to get married again and Antonia is clean and sober. How true is this? Is this a poser or is this for real? Is it just a poser trying to start rumors and screw with his groupies. Why would his daughter be on formspring & facebook talking about him and his GF. Do you think it is poser trying to make his groupies jealous."
Honestly, I think this is bullshit. I mean in his songs, he clearly wrote about how lonely he was esp in the drop the world verse and he's busy all the time. He wont have time for a bitch.LOL
