Adam Lambert has taken to Twitter to highlight the appreciation he has for his fans.

The singer has enjoyed a particularly successful 2012, with the release of second album 'Trespassing' and summer shows with Queen among the highlights.

His legion of devoted fans have given him unbridled support as he set about his endeavours and Lambert has thanked his fans their enthusiasm. He said:

"Im so thankful for my Glamberts this year! Without your Support, Energy and Joy, my endeavors would not have meant anything! 2013-MORE!!!"

As previously reported, the vocal powerhouse posted on Twitter earlier that he feels the cast of the recent Les Misérables movie adaptation should have been better singers.

The actors and actresses sang the musical's songs live on set, but Lambert believes the brave move backfired for the majority of the performances.
