Rosie O'Donnell is in no position to bash Lindsay Lohan -- at least according to Lindsay's loyal father, who claims Rosie's a washed-up failure at life ... who only stayed famous because she adopted a bunch of kids.
Michael Lohan tells TMZ, "Who the hell is Rosie O'Donnell to judge anyone, especially Lindsay, who has far more talent than Rosie ever had?"
He says, "Lindsay's talent isn't limited to being a comedian or getting notoriety for adopting and raising a bunch of kids. Sure, [Lindsay] has her pitfalls, but she is 25, and how old is Rosie?" (50, in case you're wondering).
Michael adds, "Two failed talk shows, a failed marriage, etc ... He/she who is without sin. May they cast the first stone."
As we previously reported, Rosie went on "Today" this morning, claiming Lindsay hasn't made a single good film since she was sixteen ... and isn't capable of portraying Liz Taylor in her new movie.
