Petra Ecclestone's wedding night didn't go "as planned".

The 22-year-old heiress and her new husband James Stunt's married life didn't get off to the ideal start, after the groom's best man drunkenly appeared in their hotel room and got into bed with them.

She said: "The wedding night didn't exactly go as planned. We were in bed when we heard this moaning from the corridor; it was our drunken best man, who ended up getting into bed with us for an hour and a half. There I was thinking, 'I'm pretty sure this is not how things are supposed to happen.' "

Petra - daughter of billionaire Formula One mogul Bernie Ecclestone - can't wait to have a family, and she admits she is currently sating her maternal urges with her seven dogs.

She added in an interview with the Daily Telegraph newspaper: "I definitely want three or four children before I'm 30. I think I keep buying dogs to replace children.

"We were in New York for fashion week and I was in between meetings wondering what to do, so I went and got two dogs. They're huge British bulldogs. I like big dogs."
