Sean Christopher Avery is the latest celebrity to join the Human Rights Campaign's (HRC) New Yorkers for Marriage Equality campaign.

“I treat everyone the way I expect to be treated and that applies to marriage,” Avery says in his 30-second video ad.

“Committed couples should be able to marry the person they love,” he adds. “Join me in supporting marriage equality.”

The 31-year-old Avery currently plays left wing for the New York Rangers. The Canadian-born professional ice hockey player has also dabbled in the world of fashion, interning at Vogue magazine in 2008 and working in 2009 for men's fashion label Commonwealth Utilities.

Avery is among the growing number of celebrities and prominent politicians to record a video for the campaign that began last year.

Five gay rights groups – including HRC – last month announced the formation of New Yorkers United for Marriage to begin a new push for the legalization of gay marriage in New York. The campaign will be coordinated by Governor Andrew Cuomo's office.

This week, former president Bill Clinton and his daughter Chelsea Clinton also threw their support behind New York's latest effort to legalize gay marriage.

Recent polling shows a majority (58%) of New York voters favor giving gay and lesbian couples the right to marry.
