Kate Moss and Sienna Miller are reported to have had another bust-up over the weekend.
The Mirror claims that the supermodel gave Ms Miller a piece of her mind at pal Davinia Taylor's 30th birthday party.
She was overheard telling the STARDUST actress to treat new boyfriend, Welsh actor Rhys Ifans, right saying: "If you hurt Rhy you'll have made an enemy for life.
"Treat him right and we'll leave you alone. But don't hurt him because we love him and we always stick together."
The two fashion icons have previously had a volatile relationship, initially falling out over Ms Miller dating Jude Law - Kate's good friend SADIE FROSTS ex.
But according to the newspaper the actress's spokesperson has insisted there is no problem between the girls.
Sienna and Rhys arrived at the ex-HOLLYOAKS star's 90s rave themed party, at east London hangout The Colour Rooms, together.
Other guests included Kelly Osbourne, Sadie Frost and Naomi Campbell.
