Beyonce and Jaz-Z proudly welcomed a baby girl Saturday night in New York.

According to a report by E! News, the little one's arrival came via scheduled C-section. Beyonce was admitted into the Upper East Side Hospital Friday night under the name Ingrid Jackson, a hospital staffer told the Daily News.

At a time when messages wishing the couple are flooding Twitter, fans are also excited about what the pop 'n' hip-hop princess would be called.
