Adam Lambert performs during Pittsburgh Gay Pride Weekend

Pittsburgh, PA - Singer Adam Lambert on Saturday headlined Pittsburgh's Pride in the Street Festival, a warm up event to Sunday's Gay Pride Parade and Festival.

"PITTSBURGH! I had SO much fun!!!! Thank you all for being so amazing today! Great ENERGY all around ;)" Lambert tweeted to his more than 2 million followers.

According to the Pittsburgh Post-Gazette, Lambert took the stage on Liberty Avenue in downtown Pittsburgh at roughly 10:15PM and performed a nearly 1 hour show, which opened with the single If I Had You and ended with a "dynamic" version of Whataya Want From Me.

The paper was roundly criticized by commenters for knocking Lambert over not "pouring out his heart and soul" like Melissa Etheridge had last year.

"Clearly, a heartfelt rallying cry was in order, but it seemed like he just missed the point," the paper wrote.

"WOW!" wrote one reader. "Who ate your cheerios? What a snarky review! ...This reads more like a personal attack than a review!"

"I have only one comment to say about your article of lies. Sometimes it is better to keep your mouth shut," wrote another.
