I HATE it when people refer to 20 year olds as "kids." She's a fucking adult. She doesn't need a mommy. Fucking up is part of life, it's not like she's Dakota Fanning's age or something.
LA isnt a good place for her and maybe her mother just sees her changing into something messed up and wants the best for her daughter? Regardless of age, she's still her daughter and at least someone gives a fuck about her. Paris Hilton doesn't care about Lyndsay.
Meanwhile Dina still goes shopping with her daughter's money and fires anyone who questions her daughter's need for an intervention. Her mother parties with her and uses Lindsay to get into parties! What she needs to do is what my mother would do take that little bitch aside and say "look you are not going out and you are not doing anything until you fucking sort yourself out!" I'm a couple years older than Lindsay and my mom would still do that to me. She's knows her daughter drinks. There were pictures of Lindsay on a bed with a big bottle of Jack Daniels and her mother was posing for pictures with it. Because Lindsay is the breadwinner of the family she lets her do whatever.
