Melbourne, Feb 16 : Aussie actress Naomi Watts has sparked a debate about the rigours of caesarean birth after she was photographed standing naked on a Californian balcony.

The photos, which appeared on the popular gossip website Perez Hilton, showed Watts baring not only her breasts but also a still swollen lower abdomen with a vivid caesarean scar, as she stood on a balcony with her dressing gown hanging open, reports the Daily Telegraph.

Watts, 40, gave birth to her second son, Samuel Kai, just eight weeks ago, and she was seen shooting her latest film Mother and Child in Marina del Rey.

To date, the actress has not revealed why she preferred the birthing method, keeping her and partner Liev Schreiber''s decision to themselves and not wading into the heated debate over "to push or not to push". (ANI)
