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).

She's the fifth female artist to pass the platinum mark in a week.

Lady Gaga officially hit No. 1 on the Billboard charts with her sophomore album, Born This Way.

Selling 1,108,000 copies, it has already gone platinum -- making her only the fifth female artist to do so in less than a week. (It's also her first No. 1 debut; The Fame peaked at No. 2). PHOTOS: What Lady Gaga and other stars wore to the Grammys

Here are the other female performers who have sold more than a million in less than a week:

- Britney Spears' "Oops I Did It Again" sold 1,319,000 million upon its release in May 2000.
- The Bodyguard soundtrack, featuring Whitney Houston tunes, sold 1,061,000 over Christmas in 1992.
- Norah Jones' Feels Like Home debuted with 1,022,000 in 2004.
- Taylor Swift's Speak Now sold 1,047,000 in November 2010.

NSYNC holds the record, according to Billboard's SoundScan, for most albums sold in a week. No Strings Attached debuted at No. 1 with 2,416,000  in 2000.

It's the 17th album to sell a million in under a week since Billboard's SoundScan began tracking sales data in 1991.

Gaga was widely expected to debut at No. 1 on the Billboard charts, but her record company Universal Music Group originally figured it would sell about 400,000. That number jumped to an estimated 700,000 after interest in her album nearly crashed Amazon's servers when it was sold for 99 cents.

The album has been promoted heavily, including through the Amazon deal, on Zynga's Farmville, on Good Morning America, where she kicked off the summer concert series, and in retailers like Starbucks, CVS and Walgreens. She also performed on the season finale of Saturday Night Live, on The Oprah Winfrey Show, The Ellen DeGeneres Show and in a  documentary on HBO.
