Petra Ecclestone certainly doesn't have to worry about running out of rooms for her expanding brood.


The 23-year-old socialite is pregnant with her first child, according to Us Weekly. The father is entrepreneur James Stunt, whom Petra married last year. Petra's father is the billionaire head honcho of Formula One racing.


"She is really excited to become a mom," a source says.


One thing that Petra won't be worrying about his space for her baby. Petra and James had a lavish wedding near Rome, Italy, and now reside in Los Angeles, having purchased Aaron and Candy Spelling former mansion for a reported $85 million  $82 million of which Petra borrowed from Mom. The 14-bedroom estate is known as the most expensive home in the U.S.


But who among us hasn't borrowed $82 million from our parents every now and then?
