Billie Jean King is, once again, fighting on behalf of women.

The tennis legend is speaking out against Republicans in the US Congress who she says are waging 'an epic battle' against women’s health care choices.

Tennis legend Margaret Court says that 'many, many' people are gay because they have been abused.

Court, who attended the Australian Open last week despite the uproar over some of her recent anti-gay comments, made the remark in an interview with The Sunday Mail.

Photographs of tennis legend Martina Navratilova wearing a T-shirt with a rainbow trim were mysteriously missing from media coverage, say Rainbow Flags Over Margaret Court Arena. The group, first formed on Facebook, are championing a peaceful protest at the Australian Open against the anti-same-sex marriage statements of former tennis champion Margaret Court.

Margaret Court's outspoken views against gay marriage have led some to call for the renaming the arena named after her at Melbourne Park where the Australian Open is currently underway.

But Court's former rival, openly gay Billie Jean King, is not among them.

Tennis players and fans added a splash of colour to the Australian Open today, wearing rainbow colored clothing in protest against Margaret Court's anti-gay comments.

During her match against former world number one Jelena Jankovic, British player Laura Robson showed her support for those angry at Court's vocal opposition to same-sex marriage by wearing a rainbow ribbon in her hair.

And she wasn't the only one standing up for gay rights at the tournament in Melbourne, with many fans also proudly wearing rainbows.

Tennis star Rennae Stubbs has backed gay activists who plan to protest at the Australian Open next week, following homophobic rants from legendary player Margaret Court.

The four-time grand slam doubles champion, who has been out for six years now, said people had the right to show their anger at Court, who sparked outrage from the gay community after claiming same-sex marriage legitimizes 'abominable sexual practices that include sodomy'.

In growing protests against the anti-same-sex marriage statements of former tennis champion, now pastor, Margaret Court, Dr Kerryn Phelps tweeted today: 'Time to rename Margaret Court Arena'. Dr Phelps is a high-profile advocate of LGBT rights and former president of Australian Medical Association.

Tennis greats Martina Navratilova and Billie Jean King both faced Margaret Court on the opposite side of the net during their playing days and now find themselves opposing the Australian again - this time on the issue of gay marriage.

Court, winner of three Wimbledons and a record 24 grand slam singles titles overall, is senior pastor in Perth’s Victory Life Church and is speaking out against efforts in Australia to legalize same-sex marriage.
