LOS ANGELES -- Insiders say Lindsay Lohan is behaving like a diva on the set of "Liz & Dick" and not getting along with her co-star, Grant Bowler, The Daily reported Sunday.&

Beyond her well-documented rear-ending of a truck on the way to work on June 8 and needing paramedics last week because she fell unconscious, Lohan often shows up two hours late to work and "rarely knows her lines," one source said.     &

"The crew is fed up with Lindsay because they have to spend so much time dealing with her diva antics and, in turn, trying to soothe Grant's battered ego," a source told Star magazine.&

Bowler was hired to portray Richard Burton at the 11th hour, just before filming started this month, because Lohan was demanding that cable network Lifetime bring in a big-name leading man like Gerard Butler, Robert Downey Jr. or even Brad Pitt.  &

"She was delusional," said one insider. "This is a made-for-TV movie. There's no budget for a big star."&

Lohan, biased against Bowler from the beginning, has "been so mean to Grant that her comeback is in jeopardy," Star reported.&

Lohan has looked glamorous in dozens of different '60s period costumes from "Liz & Dick," but "the footage so far has been just awful," due to the obvious lack of chemistry between the stars, said one source.&
 &
The actress' publicist, Steve Honig, told Flash, "Lindsay and the cast and crew have become a tight-knit family and are collaborating on what will be an amazing film."
