The 20-year-old dance teacher is 1/66 odds on to get the boot when the public cast their vote, according to bookmakers William Hill.

The other housemate up for eviction is wannabe footballers' wife Nikki, 24, on whom William Hill is offering odds of 14/1.

Expectations that it will be Grace who goes have been fuelled by the loud booing she got on the set of Big Brother recently - booing that the show's bosses allowed her to hear. She was very upset afterwards.

The run-up to the fourth eviction day of the series saw tensions mount in the house.

Lea was reduced to tears after a row with Nikki and Pete. The single mum said she felt rejected after she clashed with Nikki and Pete defended Nikki, not her.

The row stemmed from an incident earlier in the day when, after a house party, Mikey pinched Nikki's stash of beer and drank it.

Nikki confronted Mikey in front of Grace, with whom he has being getting close, and a massive row ensued.

New girl Susie Verrico nominated both Nikki and Grace for eviction. She was the only housemate allowed to nominate housemates for eviction.

Susie entered the house on last Friday night's live show on a Golden Ticket. Golden Tickets were hidden inside special Kit Kat bars.
