Petra Stunt has twins
Petra Stunt has given birth to twin boys.
The Formula One heiress and her husband James Stunt - with who she already has two-year-old daughter Lavinia - welcomed their sons into the world earlier this month, though their names have not yet been revealed.
A source said: "Petra welcomed not one but two bouncing babies. Both boys."
And it seems the new arrivals came as a shock to all those around the couple - including 26-year-old Petra's older sister Tamara Ecclestone - as they hadn't told anyone they were having twins.
The source added to the Mail on Sunday newspaper: "She took everyone by surprise, even her sister Tamara."
Petra and 33-year-old James - who married in 2011 - never publicly confirmed they were expecting another baby, but the socialite's growing baby bump was clear to see when she was out and about in London a few weeks ago.
Petra's father, billionaire Bernie Ecclestone, previously spoke of his delight in his daughters and grandchildren, including Tamara and her husband Jay Rutland's 13-month-old daughter Sophia.
He said recently: "I'm proud of my daughters and what beautiful granddaughters they have produced. And we are soon to be more."
