'Trespassing' hitmaker Adam Lambert has added another LGBT concert to his calendar for this summer.

The superstar is already confirmed to perform at Miami Beach's Gay Pride festival in Florida next month (April 14) and he will also take the stage at Pittsburgh's Pride in the Street event in Pennsylvania on Saturday, June 15.

Pittsburgh's Post Gazette explains that Lambert will play "a 90-minute set with a full band and dancers on the outdoor stage on Liberty Avenue" and tickets for the celebration, which are set to go on sale at 10am on April 5, will be priced at $35 each.

Yesterday (March 28), it was revealed that Lambert will be this year's recipient of the Davidson/Valentini Award at the GLAAD ceremony in May. He has been recognised for his 'fearless' attitude and commitment to fighting for equality.
