Stephanie 'Steph' Joan McMichael, born 1989, is a student from Calderstones, Liverpool. In 2002, Stephanie was disqualified from "Popstars: The Rivals", the show that created Girls Aloud, for being too young. On Day 1 of the 2008 "Big Brother", along with fellow housemates Mario, Lisa, and Luke, Stephanie was given a secret mission to hide the relationship between housemates Mario and Lisa; as part of this task she was required to pretend to be Mario's girlfriend. Failure to complete this mission successfully would result in an automatic nomination of not only her, but also Mario, Lisa, and Luke. In her role, she was required to marry Mario thinking that it was a genuine wedding; unbeknownst to her, the marriage was not actually real. Stephanie did not get on well with Mario, which resulted in several arguments between the two of them, one of which resulted in Mario calling Stephanie a haemorrhoid.

Stephanie was nominated during Week 1 because the housemates discovered Mario and Lisa's relationship, failing in her task to hide it. She became the first housemate to be evicted on Day 9 with 48% of the public vote.Its said that Stephanie and Mario did have one night of lust together that they thought no one knew about. One night late after everyone was in bed the 2 were laying together talking. The talking slowly turned in to touching as Mario fondled her tits as she groped his ass. The two continued and eventually started kissing. First very passionate then very aggressive as the two barried their tonges in each others mouths. Though the two didn't actually sleep together it was clear that her head worked down to his crotch area were the blankets were bobbing up and down. Even though they were being quite you could hear the sloshing sounds of her mouth sliding up and down his hard cock. The two tough no one knew but in the big brother house the cameras catch everything.
