Adam Lambert Blasts Some Les Miz Cast For Bad Singing

Russell Crowe and several of his famous co-stars from Les Misérables are under fire for lousy singing.

Like millions of movie-goers, America Idol 's Adam Lambert saw Les Misérables over the holidays, and he claims the hit movie "suffered massively with great actors pretending to be singers."

"Why not cast actors who could actually sound good? Sorry for being so harsh but it's so true!" said Lambert.

Lambert also says the singing should have been digitally enhanced, or "sweetened."

Now, Russell Crowe is hitting back, tweeting: "I don't disagree with Adam, sure it could have been sweetened, [the director] wanted it raw and real, that's how it is."

Lambert did have praise for Anne Hathaway, saying she was great, "Judging from her amazing rendition of "I Dream A Dream," not many would disagree.
