ROSIE O'DONNELL insists her reasons for believing Lindsay Lohan ''is not capable'' of playing the late Dame Elizabeth Taylor have nothing to do with the actress' talent.

Earlier this week the chat show host took aim at the troubled star - who is set to portray Elizabeth in TV movie 'Liz and Dick' - when she said: ''The last thing she did good she was 16. I don't think she's right for the role and I don't think she's capable at this point of doing what's needed.''

But after Lindsay - who has been in-and-out of rehab and jail since 2007- hit back with: ''It's funny that someone you don't know at all can say something so intrusive and so knowing,'' Rosie explains her comments were borne of concern, not criticism.

Appearing on the 'Today' show, she said: ''I [was] watching Whitney Houston's funeral, and I remember thinking, 'Why didn't more people say what they knew?'

''We all knew, when she would not show up to do this show, not show up to do my show, we watched 'Being Bobby Brown' and it was like watching Sid and Nancy, they were people who were in the throes of addiction.

''But all that anyone cared about was that the show was getting ratings, not that this woman, this talented individual, this human being, this mother, this daughter, was worth saving.

''To look at Lindsay Lohan, you can't help but feel for her. I don't think she's untalented, I think she's quite talented.''
