Big Brother's Sylvia and Mohamed nominated for eviction
Sylvia, 21, has accused Mohamed of asking to pretend to be lovers in order to sell their story to the magazines and make money once they're evicted.
New arrival Stuart was exempt from nominations, while Mario has dodged a bullet yet again, escaping eviction for the third week running.
In the first week Mario went up against lover Lisa, and fellow housemates Stephanie and Luke.

The public voted for Steph to leave after the four failed the Wedding Task.
In the second week, Mario went head to head with Alexandra, who was removed by Big Brother before the live eviction after producers deemed her behaviour threatening.
Meanwhile, the housemates have been given a new task - to recreate U.S. rockers OK Go's famous treadmill music video.
After being given a generous lie-in until 11 in the morning on Tuesday, the fifteen contestants were roused from their sleep with the OK Go's hit 2006 song Here It Goes Again.

The clip features the band performing an elaborate choreographed number on several treadmills in a single continuous take.
It reportedly took the band 17 takes to get it just right, but their efforts paid off as the video won a Grammy Award in 2007 for best short-form music video and has since been viewed over 36
million times on clip sharing site YouTube.
As a group, the housemates have a less-than-perfect track record with previous tasks, which usually end up in rowing matches between the more hot-headed contestants.
But perhaps winning last week's 24-hour Japanorama Task, which earned them a luxury food budget, has put them in good stead.
