Lisa, Kris become official housemates

Lisa and Kris have become the third and fourth contestants to become official Big Brother 10 housemates.

The decision was made when Big Brother telephoned the house and Lisa was the first to pick up the call.

She was informed that she had 15 minutes to choose someone else to join her as a housemate, but was also told that she must keep her decision secret for that time.

Big Brother then spoke to the house and announced that Lisa was the third housemate and asked her who she had picked as the fourth.

When she announced that she had chosen Kris, the houseguests cheered and congratulated them before they were called to the Diary Room.

Lisa and Kris join Rodrigo and Noirin, who attained full housemate status earlier in the evening.
