Adam Lambert pledged Tuesday to obey Malaysian government rules that forbid the flamboyant, openly gay glam rocker from kissing anyone onstage at a planned concert this week, but called it "a tough decision."

The "American Idol" runner-up, who is touring Asia, told The Associated Press in Hong Kong that his "main goal is to keep people entertained - not to make them uncomfortable." Lambert is slated to perform Thursday at a stadium in Muslim-majority Malaysia's biggest city, Kuala Lumpur.

Lambert has agreed to heed restrictions against stripping, jumping and kissing onstage, said Yuen-See Cho, a representative for concert co-organizer Sony Music Entertainment Malaysia.
