Lindsay Lohan is beyond thrilled to be playing Elizabeth Taylor in the upcoming Lifetime movie Liz and Dick, and she's ready to talk all about it!

The 25-year-old starlet is fighting back against Rosie O'Donnell's criticism ... in which the 50-year-old talk show host said Lilo was "incapable" of playing the screen legend.

In response to Rosie's slam, Linds said:

    "It's funny that someone you don't know at all can say something so intrusive and so knowing ... I know that I'm great. I know that I know Liz Taylor very well, and I share the same makeup artist and the same hair stylist. We've worked with a lot of the same people."

As for who will be playing Richard Burton in Liz and Dick, listen to Lindsay's response.
