Pop icon Lady Gaga has finally arrived back in the USA following the first part of her world tour with the Born This Way Ball.

She was photographed returning from Australia earlier this week after her final date in the country, which took place on July 8 in Perth, and stepped out from the airport in Los Angeles wearing only black underwear, a pair of black sheer tights and a leather jacket.

Gaga can also be seen holding her middle fingers in the air (pictured below) as a swarm of photographers surround her. According to her official website, she is set to resume her year-long tour schedule on August 14 in Bulgaria before taking her provocative new live show to Finland, Austria, Sweden and the UK.

On July 8, the 'Marry The Night' sensation took to social networking site Twitter and shared a photograph of herself (above left) with her 26.8 million Little Monsters around the world, which she accompanied with the caption:

"After tonight's show, I'll have performed for 200,000 Australians in 1 month. ‪#BornThisWayBall‬"
