I Wanna Play!

I am a copy-cat. I wanna play 3 truths and a lie too:

1) A boy once dumped a famous female rock star because he wanted to date me instead;
2) A major recording studio owns a song about me;
3) I am related to Winston Churchill;
4) I once had a gig as a personal shopper for ritzy clients while working at a department store, one of my regular and favorite clients was a governor's wife.

So, which 3 are real? Do you know?
