Big Brother housemate Mario Marconi is the odds-on favourite to be evicted on Friday night.

The 43-year-old Sylvester Stallone lookalike – who faces the boot alongside girlfriend Lisa, pop wannabe Steph and cheeky chappy Luke – has seen his odds go from 1/2 to 4/11, according to bookmakers Ladbrokes, after he reduced Jen to tears.

Jen, 22, and Steph, 19, stripped to their underwear to pose as the Cheeky Girls as the housemates played a game called BB’s Got Talent. But Mario – real name Shaun – branded them ‘tarts’, leaving Jen sobbing and Steph furious.

But it seems that readers do not agree with bookmakers, with Steph storming ahead in our poll as the favourite to get the boot with 45 per cent of the vote.

Housemate Alexandra, 23, is currently being branded the BB b****, with many viewers complaining to both Ofcom and Channel 4 after she shouted at Rebecca for burning chips and made Rachel cry.

Big Brother called Alex to the Diary Room and reprimanded her for her behaviour.

Ladbrokes spokesman Robin Hutchison said: “With Alexandra not being nominated, Mario looks most likely to be the first out.”

Steph is second favourite to go tomorrow with odds of 2/1 while Lisa and Luke appear safe with odds of 16/1 and 50/1 respectively.

The four were put up for eviction when they failed to fool the other housemates in the secret task they were given. They had to convince everyone Steph was Mario’s girlfriend and not Lisa.

Thai housemate Kathreya is the current favourite to win the reality TV show, with odds of 3/1. She is also a hit in the house as she keeps giving everyone Thai massages.
