Russell Brand's socialite girlfriend Jemima Khan has praised her teenage son for thwarting an attempted break-in at their home.

Khan, who has been dating the actor/comedian on and off since last year (13), has revealed one of her boys, who are aged 15 and 17, was at home when burglars attempted to gain access to the property in the early hours of the morning.

The 40 year old writes in a post on on Friday (06Jun14), "2am break-in, thwarted by son. Told not to put spikes on gate to prevent repeat as I'll be liable if intruders get injured."

Khan gave no further details about the incident. She is believed to own a family home in south west London as well as a mansion in Oxfordshire, England. Her sons are from her marriage to Pakistani cricketer-turned-politician Imran Khan.
