Adam Lambert's gym time is obviously paying off.
The 33-year-old singer has been taking to Instagram to shares a few gym selfies with his fans, showing off his clearly more muscular physique.
"Gym time back in Hollywood," he posted, pulling down his tight-fitting blank tank top.
But he took it one step further on Sunday, when he went shirtless for this intense pic.
Perhaps he's gearing up for promotion for his third album, The Original High, which is set to hit shelves this summer. The first single will be released in April.
"I wanted something more internal and more grounded," he told Billboard about his highly anticipated new album. "A little less with the theatrical and the camp and the presentation. I wanted to bring it in a bit more."
The "Whataya Want From Me" singer filled in as a guest judge for Keith Urban on this season of American Idol, when he blew judges Jennifer Lopez and Harry Connick, Jr. away by re-auditioning for them singing the Queen classic "Bohemian Rhapsody."
