Lady Gaga wants to be the voice of her generation and address the big issues in the world.

The 24-year-old singer revealed in a video blog about the US military's policy of 'Don't Ask, Don't Tell' ' which requires gay service members to keep quiet about their sexuality on the proviso they won't be asked about it ' that she wanted to represent her generation and those affected by the policy.

Discussing the upcoming US Senate vote on the legislation, she said: ' am here to be a voice for my generation. Not the generation of the senators who are voting but for the youth of this country, the generation that is affected by this law, and whose children will be affected.'

The eccentric pop star wore a suit and sat in front of a US flag to deliver her message, and highlighted startling information that military chiefs were searching through people's personal emails and belongings to discover their sexuality.

She said: 'Ultimately, the law is being enforced using gay profiling. And gay soldiers have become targets. In short, not only is the law unconstitutional but it's not even being properly or fairly enforced by the government.'

Gaga has long been an impassioned speaker on gay rights issues, and was recently reported to be training to become an ordained minister so she could marry her gay fans.

A friend said: 'She has completed virtually all of the coursework. She sees this as a way of repaying the love her fans have shown her."

If Gaga ' who was raised as a devout Catholic ' were to complete the online course, she would be able to refer to herself as a 'pastor or reverend'.
