Mariah out for her CD release party (April 22).

Celebrating her own success, Mariah Carey made her way to a big CD release party in downtown New York City on Tuesday evening (April 22).

Dressed in a sexy black outfit with diamond encrusted hoop earrings, the Grammy-winning singer was running a bit late for her late night affair - but still made an effort to pose for photographs along the way.

And Mimi had good reason to be in high spirits, as she scored her sixth No. 1 album on the U.S. pop chart Wednesday, sending her straight into the record books.

According to Reuters, “E=MC2 sold 462,971 copies during the week ended April 20, the best debut sales week of her career and the strongest week by any artist so far this year.”

As a result, the 38-year-old diva “is now tied with Madonna and Janet Jackson for the second most No. 1 albums among female artists. Barbra Streisand, with eight, leads the pack.”
