Facebook adds same-sex marriage icon

Same-sex couples will now be able to show friends their marriage status on Facebook after the addition of new icons.

The icons show two brides side by side and two grooms side by side above the word "Married".

Facebook co-founder Chris Hughes updated his timeline with the same-sex icon after tying the knot with his partner Sean Eldredge at the weekend.

His friend and fellow Facebook founder, Mark Zuckerberg, was among the people to 'like' Hughes' new status.

Until now, homosexual Facebook users had the option of displaying 'In a Civil Union' or 'In a Domestic Partnership' on their timelines to show their relationship status.

Selecting 'married' before now would have displayed an icon with a heterosexual couple.

This is the first time same-sex couples have been able to declare themselves married.
