Adam Lambert believes legalizing marriage for gay and lesbian couples is an economic issue.

The 30-year-old Lambert is set to headline a fundraiser concert to benefit Marylanders for Marriage Equality, the group working to uphold a gay marriage law approved by Maryland lawmakers.

“Ideally, that's what being an American is – that we all have a shot [at marriage],” he told gay weekly Metro Weekly.

“I hear a lot of arguments against it, where [gay activists] say, 'We should be focusing on economic issues and not human rights issues, for the election.' There's some value in that. But I also think, 'You know what? This is an economic issue for gay people.' We should have the same right as a straight couple to have a tax exemption. … We should be able to raise a family that's equally protected under the law,” he said.

The concert will be held on Tuesday, September 25 at the 9:30 Club, the legendary live music club located in the U Street neighborhood of Washington, D.C. Tickets, which start at $125 and go up to $250, can be purchased through or at the 9:30 Club.
