A 5.4 magnitude earthquake in Los Angeles shook the American 'Big Brother' house on Tuesday.
Contestants were lounging in the garden and socialising in the kitchen area of the house, which is similar to the design used by the UK 'Big Brother'.
When the quake began, the housemates all ran outside and stood in the middle of the garden, with one saying; 'Oh my God, the ground is shaking'.
No injuries or damage to property occurred.
It has been reported that a taping of 'Judge Judy' was also disrupted by the same earthquake.
