TWO housemates will get the boot tomorrow in a surprise eviction.

Big Brother viewers have been voting for a winner since last Friday, and the two contestants with the lowest support will get kicked out on Tuesday night in an eviction which has been kept secret from the housemates.

Moaning Mo and happy Kat are the favourites to get the axe in the eviction, which will leave five housemates left to battle to win the show and the £100,000 prize.

Mikey is the new favourite to win, with some bookies offering odds of 6/5 for him to clinch the crown.
