Lindsay Lohan has yet to visit her dying grandfather in hospital, according
to her father Michael.

The 'Mean Girls' actress was planning to visit the New York hospital where
Richard Lohan, 73, is being treated for terminal colon cancer, but Michael
claims the 21-year-old beauty is being prevented from making the trip by her
mother Dina.

He said: "Dina is still making it hard as hell for me to see my children.
Even though my father is dying, my parents still haven't seen my children.

Dina told me, 'It's up to the kids if they want to see their grandparents.'
But she's made no effort to put them in touch or make this happen. That is
the bottom line."

Michael revealed Lindsay, her sister Ali and brother Cody have also not seen
their grandmother Marilyn, Richard's wife, who was involved in a car crash
over the Easter holidays.

He said: "My mother Marilyn was flown by helicopter to the hospital on
Easter Sunday after hitting a telephone pole and tree. Also, my father went
into heart failure again yesterday - and yet not one of the kids has seen
him."

Michael, a born-again Christian, also revealed he is planning to sue Dina
over her upcoming reality show 'Living Lohan', set to premiere on US TV
network E! this summer.

He added to the New York Daily News newspaper: "It's the exact same show I
pitched. She even used my title."

A representative for Lindsay is yet to comment.
