Let's review the similarities:
Headline-making lesbian relationship with a DJ. We suspect Lohan and Samantha Ronson are just a bit more serious than Geldof and her buddy Fifi Brown, who DJ together as "Trash Pussies." Geldof and Brown make Facebook quips about getting married; Lohan and Ronson have angry fights throughout New York and London.
Nude pics. Lohan took off her top for New York magazine in an oh-so-artistic homage to Marilyn Monroe. Geldof took hers off, apparently for a paparazzo, and was featured in an oh-so-artistic tour of her tattoos (sorry, "body art").
Geldof of course is unlikely to take the one big step needed to truly live like Lohan: Earning all that money she blows.
