True Blood star Anna Paquin has celebration LGBTI Pride Month with a tweet celebrating bisexuality.

The 31-year-old actress posted a message that included the pink and red marriage equality symbol.

‘Proud to be a happily married bisexual mother. Marriage is about love not gender,’ Paquin tweeted, alongside the Twitter handles for Equality California, the It Gets Better project and NOH8 Campaign.

The actress, married to True Blood co-star Stephen Moyer, admitted she forgot it was Pride month in Los Angeles.

‘Been obsessing so much bout @socceraid @_smoyer forgot it was #gaypride in LA! I’m proud of the steps we’ve taken 2wards equality! R U?,’ she tweeted.

She was referring to her husband’s participation in a celebrity soccer match that raised millions for UNICEF.

Paquin came out as bisexual a few months before her 2010 marriage in a public service announcement for the Give A Damn campaign.

‘I’m sure for some people saying they’re bisexual feels less scary than making a statement that they’re gay,’ she told Zooey magazine. ‘For me, it’s not really an issue because I’m someone who believes being bisexual is actually a thing.’

‘It’s not made up,’ she added. ‘It’s not a lack of decision. It’s not being greedy or numerous other ignorant things I’ve heard at this point. … For a bisexual, it’s not about gender. That’s not the deciding factor for who they’re attracted to.’
