First-week sales of her "Born This Way" album could hit 1 million units as Amazon learns a lesson from trying to sell it for 99 cents (its servers crashed).

The pop star sang a part of "Born This Way" and called herself "a child of diversity."

Europride got a taste of Lady Gaga when she appeared at Saturday night's pride rally at the ancient Circus Maximus in Rome to denounce LGBT discrimination.

Decked out in a green wig and a plaid skirt, the pop star sang and performed a few bars of "Born This Way" on the piano before calling for an end to homophobia, according to the Associated Press.

"I am a child of diversity," she declared, which she said was her response to the question, "How gay are you, Lady Gaga?"

She embraced her Italian ancestry and told the tens of thousands of protesters in attendance that their "great courage" inspired her. She singled out the Middle East, Poland, Russia and Lithuania among others as areas guilty of intolerance towards gay and transgender people.

According to organizers, Rome was chosen because of its association with the Vatican, which has historically opposed same-sex rights.

Gaga's display of camaraderie for the gay community comes days after comedian Tracy Morgan was criticized by fans and celebrities for making anti-gay remarks at a Nashville show.
