Adam Lambert Faces New Lawsuit Amid 'Queen' Performance [VIDEO]

Adam Lambert comes face to face with a brand new lawsuit that suggests the singer violated the rules on American Idol, when he appeared on the reality shows eighth season.

Colwel Platinum Entertainment, who has been marketing Lambert's new album 'Beg for Mercy,' claims that Lambert was under a Music Services Agreement and Co-publishing Agreement with another company prior to his success on 'American Idol'

Upon further information and belief, the rules governing appearances on and participation in American Idol when Lambert was a contestant provided, among other things, that contestants were ineligible if 'as of the date of [the] audition, [they had]...a music recording contract...or any other contractual arrangement that would prohibit [them] from entering into a...recording contract.. the record label said in a written statement, the Hollywood Reporter reported.

Details of the lawsuit reveal that Colwel Platinum Entertainment's parent company, Welsford, spent over $200,000 on full rights to produce Lambert's recordings and have rights to his name, nickname and biography. But as the label started to work on the artist's new album they found overlaps with a previous album named beg for mercy, which Lambert's reps took down from Amazon.com, where the record was being sold. Colwel also claims that Lambert uploaded 13 songs to his MySpace page without authorization.

The dispute spurred great discussion on Twitter, which lead Lambert to tweet, Beg For Mercy project is same as 'Take One'. Some songs I worked on 5 yrs ago and never finished. This release comes as a surprise to me...Lambert is yet to release an official statement about the lawsuit but has been tweeting cryptically since the claims surfaced. Remember than in any dispute, reserve judgment until all the facts surface from ALL parties. Guilt and innocence come with a complete story, he tweeted on Nov.5.

Meanwhile, Lambert took to the stage with Queen guitarist, Brian May, on Sunday night at the MTV Europe Music Awards, performing a medley of hits including Show Must Go On, We Will Rock You, and We Are the Champions.

During the eighth season of American Idol, Lambert citied Freddie Mercury as a key influence in his own music, auditioning for the show with Queen's Bohemian Rhapsody. Over 8,000 people watched in Belfast and a further 1 million across the globe on television as Lambert performed in an eight-minute performance.

What an enormous honor to sing w QUEEN! I could feel the spirit of Mercury alive on stage tonight! Thank u Brian and Roger and crew. LOVE, Lambert tweeted after his performance. I'm a proud QUEEN, he added.
