After kissing Jemma Lucy, 28, in a passionate game of Spin The Bottle, the Girls Aloud singer soon found herself smooching her Celebrity Big Brother bed buddy Chad, 30.
Once again ins scenes set to air tonight, Sarah finds herself in the firing line from Jemma after refusing to kiss Sam Thompson, 25, in front of his romantic interest Amelia Lily, 22.
In turn, after a day of blazing rows with almost all of her housemates, Sarah finds solace in Chad as they cosy up in the toilet.
“The only person I feel comfortable around is you, and you don’t want to get involved either,” she tells him.
However, in a matter of seconds, kissing noises creep from beneath the bathroom door and Sarah hops into Chad’s bed for more tongue on tongue action.
What’s more, Sarah spent her afternoon giving Chad a sensual neck massage while he enjoyed himself completely naked.
Sarah has come under fire from Celebrity Big Brother viewers as it emerged she had a “secret” boyfriend watching on from outside the Borehamwood bungalow.
Despite the 35-year-old stressing that she’d only been dating the elusive mystery man for a mere four weeks, her kisses with Chad appear to have put a dent in her chances of winning CBB.
Tonight sees Jemma, Sam, Jordan Davies and Helen Lederer all face the public vote with one of them becoming the second housemate to be evicted from the Elstree compound.
Celebrity Big Brother continues tonight at 9pm on Channel 5.
