Sugababe is reportedly being threatened with the sack only 18 months after joining the band.
The singer has apparently “gone underground” over pressure from all sides to dump her boyfriend Freddie Fuller, who is currently awaiting trial for the alleged rape of her 20-year-old sister Samiya.
A source tells the Sunday Mirror, “The other two girls, the management and the label have threatened to axe her unless she dumps him.
"She's gone underground and has refused to answer their calls - but it will all climax this week.
"Amelle has got a serious decision to make."
However, a spokesperson for the Sugababes says, "As far as we're concerned, it's business as usual."
