Socialite Petra Ecclestone reportedly gave birth to a baby girl in secret earlier this month (Mar13).

Ecclestone is said to have welcomed a daughter, her first child with husband James Stunt, in early March (13) after pink balloons emblazoned with the slogan 'Baby Girl' were spotted at her London home.

She emerged in public for a shopping trip in Beverly Hills, California on Monday (25Mar13) and was clearly without her previously visible baby bump.

The 24 year old, daughter of Formula One boss Bernie Ecclestone, never confirmed her pregnancy. She married businessman Stunt in Italy in 2011.
