Same thing Lisa Marie Presley is famous for. They are the daughters of someone famous, that is all.
A better person to compare her to would be Paris Hilton. The difference between the two, from what i've seen, is Paris actually seems to have a business head on her shoulders and has successfully earned her own money via her brands.. where as I think Tamara desperately wants to do that but hasn't managed to so far. She has certainly tried to 'launch' herself as a brand over the last couple of years and when your Dad has as much money as he does.. I wonder sometimes if the media wheels are oiled, so to speak.
I like her. She's harmless really. I hope she is happy. It must be strange growing up and living in a world with so much money and luxury.
