Singer and television star Kelly Osbourne has reportedly warned Dannii Minogue to stop "bad-mouthing" her mother Sharon.
According to Digital Spy, Osbourne referred to rumours of a feud between her mother and Minogue by saying: "Dannii is spineless really.
"She said nothing to my mum's face and even gave her an end-of-series gift.
"If she does not stop bad-mouthing her she will have me to contend with."
