Elton John and George Michael have had albums debut at number one on the Billboard charts but neither were openly gay at the time. So Adam Lambert made some history on Wednesday (23 May) when his album Trespassing opened in the top spot on the Billboard 200 chart.
By selling 77,000 copies, Trespassing dislodged Carrie Underwood's Blown Away and outperformed Lambert's first album, For Your Entertainment, which had debuted at number three.
'Thank you to the Glamily for helping me make HISTORY!' Lambert tweeted to his 1.5 million followers on Twitter.
Lambert is the seventh American Idol finalist to reach No. 1, following Kelly Clarkson, Ruben Studdard, Clay Aiken, Underwood, Chris Daughtry and Scotty McCreery.
In February, the singer had announced to fans that his sophomore album would not be out on March 20 after all explaining that he was 'working on some new songs, making the album even better!'
Trespassing is a more personal disc than his 2009 album For Your Entertainment which sold nearly 2 million copies worldwide.
Lambert has described the second album as 'an exciting journey through the past two years of my life. It's been a transformative period and I really wanted to make music from what I've experienced. All these songs honestly explore the ups and downs of my reality.'
In addition to co-writing many of the tracks, Lambert collaborated with an all-star list of artists, producers and songwriters including Pharrell Williams, Dr. Luke, Bruno Mars ,Claude Kelly, Benny Blanco, Bonnie McKee, Nile Rogers, and Sam Sparro.
