Petra Ecclestone, may be keeping mum about her pending motherhood, but she was clearly sporting a baby bump as she stepped out in Los Angeles on Sunday.
The blonde heiress was spotted leaving Madeo's restaurant in West Hollywood after enjoying a meal with her mother, husband and actor Mel Gibson, the Daily Mail reported.
Opting to wear a loose-fitting grey printed top failed to hide her blooming baby belly.
The 23-year-old sported a stylish short leather jacket over the top and completed her look with a comfortable pair of black leggings with wedged fringed boots.
She was reportedly joined by Braveheart superstar Mel Gibson, who according to eyewitnesses left via a different exit following the dinner with the billionaire family.
Petra and husband James Stunt are said to be expecting their child in March 2013. (ANI)
