International pop star Lady Gaga will highlight issues of equality when she serves as guest editor for all editions of the Metro newspaper on May 17.

Stockholm-based Metro, which announced the guest stint on Thursday, is produced in 20 countries and publishes as a free transit newspaper in eight Canadians cities.

A vocal supporter of the lesbian, gay and transgendered community, Lady Gaga will focus on equality and individuality in her stint as editor-in-chief for the global edition, Metro said in a statement.

Working from the London office of Metro World News, she is expected to select stories and provide comments on breaking news. Metro will run a competition to select an editorial assistant for her one day on the job.

For the competition, the pop singer is riffing on her newest hit Born This Way and asking readers to write about equality issues that affect them. 

"Let's see how fans would define what Born This Way is for them,"  she said. 

"I say I was born to be brave. That's part of my mission in life. I was born to follow my artistic visions. Look into yourself. Are you born to be brave?"

She follows in the footsteps of fellow singer James Blunt, who served as Metro's guest editor in 2008. Huffington Post co-founder Arianna Huffington served as a guest editor for Metro's U.S. edition in 2009.

Metro claims 37 million readers in cities around the world. The paper has editions in Vancouver, Calgary, Edmonton, Winnipeg, London, Ont., Toronto and Halifax.

Lady Gaga, who maintains a popular Twitter feed, will also begin writing a column for art and fashion magazine V.
