Michelle’s under-the-sheets antics could prove to be her downfall – she is now the girl most likely to get evicted from the Big Brother house.
The Geordie remains besotted with psychology student Stuart after spending two lustful nights with the 20-year-old.
But her tryst has sparked trouble with rival women in the house, and now even Stuart appears to be cooling off.
Bookies say Michelle, aged 23, has lost public votes by getting down and dirty with Stuart.
She is now the favourite woman to be evicted from the house at 4-1.
Ladbrokes spokesman Warren Lush said: “There’s always the danger that a bit of rough and tumble in the Big Brother house can work against you.
“The majority of the voting public are women and they probably want Michelle to play it a bit cool.”
Former head boy Stuart may have also lost public support because of his nights of passion with the mortgage adviser and wannabe glamour model.
Mr Lush said: “I can’t see Stuart winning the show now. I don’t think any individual who becomes part of a couple can win.”
Meanwhile, Stuart appears to have given Michelle the brush-off after insisting on sleeping alone on Saturday night.
Michelle told housemate Victor: “I’m finding with Stu he doesn’t avoid me, but I would expect there would be more contact.
“Why does he say those things and then, the next night, he doesn’t want to be next to me?”
South African-born Vanessa and posh Glasgow student Shell have not taken a shine to Michelle and both say they cannot understand why she was chosen for the Channel 4 show.
Vanessa and Shell have become inseparable and shared a bed together with Jason.
Meanwhile the Big Brother housemates have been set their second weekly task – to run a 24-hour fast food take-away.
Ahmed remains odds-on favourite to go at the next eviction at 4-7 while Marco is third favourite at 7-1.
