Spears, 23, accompanied by Federline, 27, checked into an undisclosed hospital at about 6 a.m. where she underwent a C-section, E! Online reported.

The couple wed last year only a few months after Spears' 55-hour marriage to childhood friend Jason Allen Alexander and the birth of Federline's second child with actress Shar Jackson, E! said.

Spears' new fragrance, Fantasy Britney Spears, is due to launch Thursday. She has described it as a "completely magical" blend of "enchanting scents and flavors" with "a hint of cupcakes," E! said.
