Michael Lohan & Rosie O'Donnell

Miaow. It's clash of the Irish Americans as Michael Lohan, father of the troubled starlet Lindsay, lashed out this week at Rosie O'Donnell.

Lohan was responding to O'Donnell's rejection of his daughter's fitness to play Elizabeth Taylor in a new biopic.

O'Donnell is in no position to bash Lindsay fumed Lohan senior, countering that Rosie's a washed-up failure at life and she only stayed famous because she adopted a bunch of kids.

Lohan  told TMZ, 'Who the hell is Rosie O'Donnell to judge anyone, especially Lindsay, who has far more talent than Rosie ever had?'

'Lindsay's talent isn't limited to being a comedian or getting notoriety for adopting and raising a bunch of kids. Sure, she has her pitfalls, but she is 25, and how old is Rosie?' (50, if you're wondering).

Lohan added: 'Two failed talk shows, a failed marriage, etc. He/she who is without sin, may they cast the first stone.'

Rosie tore up the 'Today' show on Tuesday morning, claiming Lindsay hasn't made a single good film since she was 16 and simply isn't capable of portraying Liz Taylor in her new movie.
