UPDATE: Lambert Slams 'Les Mis,' Crowe Responds

Adam Lambert was one of the Americans who forked over millions ($66 million, to be exact) to see Les Miserables over the Christmas holiday and his 9 Tweet review of the film garnered a lot of attention over the weekend.

"Les Mis: Visually impressive w great Emotional performances. But the score suffered massively with great actors PRETENDING to be singers," Lambert wrote on December 30. "It's an opera. Hollywoods movie musicals treat the singing as the last priority. (Dreamgirls was good). Anne Hathaway as Fantine and Enjolras were the exceptions for me. Helena B Carter and Sasha B Cohen were great too. And I do think it was cool they were singing live- but with that cast, they should have studio recorded and sweetened the vocals. I felt like I should ignore the vocals and focus on the emotional subtext- but the singing was so distracting at times it pulled me out. The industry will say 'these actors were so brave to attempt singing this score live' but why not cast actors who could actually sound good? Sorry for being so harsh but it's so True!"

Now, an unexpected ally has taken Lambert's side in this debate: Les Miserables star Russell Crowe!

Last night, @BrunetteMom123 Tweeted at Crowe, "Not sure if you saw @adamlambert's comments about Les Miserables. He was pretty opinionated."

The Oscar-winner responded, "I don't disagree with Adam, sure it could have been sweetened, [Les Miserables director Tom] Hooper wanted it raw and real, that's how it is."

On Wednesday, the singer took back to Twitter to once again talk about the movie.

"My movie review has gone viral. U can spend a whole year praising artists for inspiring work, but one critique gets all the attention. Funny," Lambert tweeted, continuing, "Those raw and real moments when characters broke down or were expressing the ugliness of the human condition were superb. However... My personal opinion: there were times when the vocals weren't able to convey the power, beauty and grace that the score ALSO calls for."

Lambert then shouted out to the original Broadway cast, "I guess I'm a purist for the original LIVE broadway recording when the actors sang the f*ck outta those songs. JUST an opinion... "

And that's when Lambert decided to put the whole thing to rest, "I should prob stop fanning the flames on this one..but i love a good debate- couldnt help myself," adding finally, "One last thing though: Anne Hathaway was so good- had me tearing up. Oscar worthy performance for sure! Ok. #donediscussinglesmiz."

No response yet from Crowe or the cast.

What do you think? Was Adam Lambert right, or was the live singing part of the film's charm? Weigh in below!
