Big Brother housemate Sara Folino took to the bleach in an attempt to keep her mind off love interest Darnell Swallow.

The feisty Australian decided to dye her moustache blonde, much to the amusement of her fellow contestants.

Sara, 27, has continued to stir up tensions and her behaviour in the house has become a major talking point. However, fellow contestants are now questioning her close relationship with Darnell.

In the last few days, the pair have engaged in a series of saucy antics, including her straddling the sexually frustrated albino in bed.

Kat, in particular, is not impressed by Sara's behaviour - and believes Darnell could get hurt.

'I can see it's not going to happen. I'm not kidding. I don't want him to get hurt, because he is my friend.'

Mohamed has also voiced his concerns for his pal, telling the group Darnell was 'falling in love' but his feelings would go unrequited.

Last week, Rex branded Sara as a 'dirty little tramp', adding 'get back in your hole, you dirty little badger.'

However, it remains to be seen whether Sara's new take on female grooming will do anything to dampen Darnell's enthusiasm.
