Lady Gaga's baby name revealed.

A US media outlet obtained the birth certificate for the Poker Face singer's first child, all but officially confirming the baby's arrival. Gaga, whose real name is Stefani Germanotta, and her entrepreneur partner Michael Polansky, have yet to comment on reports they recently became parents. However, the documentation, newly unearthed by TMZ, indicated that on 9 June at 11:19 PM, baby girl Rose Bean Polansky was delivered at Cedars-Sinai Medical Center in Los Angeles. The document also explained baby Rose was delivered by Dr Robert Katz - famously an obstetrician to the stars.
