The much-awaited day of all Lady Gaga fans in Australia has already arrived. Tonight, the Sydney Entertainment Hall is the setting for Lady Gaga's one-time-only "monstrous" performance.

"Little Monsters" all over Australia are gearing up for the best night of their lives as they line up as early as now to watch the US singer belt it out on stage. Lucky fans who won a pair of tickets through different online and offline competitions by sending photos of themselves dressed like the singer are more than excited to see their idol live. "I have been waiting all my life for this!" says one fan; while another "I can't believe I'm seeing Gaga tonight!" says another.

Gaga, the country's latest honorary citizen arrived on July 9 via her private plane. The singer wore a white gown with puff sleeves and leather corset as she walked down her plane to greet fans, photographers and the media. On the taping of the US singer's first television appearance, she blatantly urged Aussie lawmakers to "get on with it", pertaining to same sex marriage. Lady Gaga's hometown of New York is the sixth state in the United States to allow marriage equality, and it seems the singer wants to inspire every nation to do the same.

The celebrity news section of the Herald Sun will post a video of the Sydney Monster Ball in its entirety on July 29th on their website. The HS will also post exclusive behind-the-scenes footage, with commentaries from the people who made the event possible.
