Lisa AppletonIt's been drama-tastic in the Big Brother house this weekend.

First off, there's been a game of musical chairs with housemates coming and going.

And then at 2am on Sunday morning, everyone was evacuated from the house.

Sleepy BB contestants were hauled out of their beds in the middle of the night, spending two hours outside after a security alert.

Live feed was cut and police were called to the set in Elstree, Hertfordshire, during the incident, which is rumoured to have occurred following a phone call from a member of the public.

Lisa Appleton was one of the housemates who was fast asleep during the incident.

A BB spokesperson said: "Due to a security incident, it was necessary to remove the housemates from the Big Brother house as a safety precaution. After the necessary checks were made, housemates returned to the house without incident.

Earlier on at the weekend, Jennifer Clark was booted out by the public vote, following a week of tears, tantrums and some of the most chronic moaning ever witnessed in BB history.

After losing the eviction run-off between her and Rex Newmark, Jen trotted off to the outside world, to be greeted by overwhelming chorus Sara Folinoof boos from the waiting crowd.

In her post-exit interview, Jen admitted to Davina McCall that she was a bit gutted by the publics' reception, saying:

“It’s hard and you think what have I done. Have I offended anyone?”

Meanwhile back in the BB den, Stuart Pilkington and Dale Howard (who Jen admitted she rather likes) were left moping after the brunette's exit - but not for long.

No sooner had the dust settled on her eviction, than three new ladies were sprung onto the unsuspecting housemates.

First up of the BB newbies was Sara Folino, 27, a self-confessed loud-mouthed Aussie and Angelina Jolie lookalike.

Then followed Maysoon Shaladi, a 28-year-old model from Hertfordshire, with "both beauty and brains".

And finally, 44-year-old Belinda Harris-Reid, a theatre director from Exeter, popped by to complete the surprise.

The housemates were absolutely gobsmacked by the new arrivals - especially the blokes, who probably couldn't believe their luck.

But will fresh blood bring fresh drama? We can hardly wait to see.
