It's safe to say that the battle lines have been firmly drawn between the old Sugababes (or MKS as they're now calling themselves) and the current line-up.
Mutya Buena, Keisha Buchanan and Siobhan Donaghy gave 'babe member Heidi Range the cold shoulder as they were thrown together at V Festival over the weekend.
The girls had managed to keep apart as they partied on different sides of the Virgin Media Louder Lounge at the event in Chelmsord, Essex.
However, when Mutya and Keisha spotted Heidi, who was with Emma Bunton and Leigh Francis, they walked off without so much as exchanging a hello.
"It was a really obvious snub," said an eyewitness. "There's clearly no love lost between them and Heidi."
