Kate MossKate Moss and Sienna Miller reportedly had a drunken argument at a friend’s wedding at the weekend.

According to onlookers, jealous Kate was initially angered by seeing that their mutual friend Rhys Ifans had accompanied Sienna to the reception in London and that caused her to dwell on other issues between the pair. She was spotted shooting evil looks across the room until couldn’t hold her tongue any longer.

An onlooker told the Sun: “Kate had a go at Sienna and accused her of stealing her style. She was ranting on about how Sienna was now trying to steal her lifestyle and her friends too.”

“It was really cutting and everyone was listening to them. A few drinks had been sunk by the time Kate said it and Sienna had plucked up some Dutch courage too. She gave Kate as good as she got.”

When the pair’s war of words started to get vicious, Kate’s friend Sadie Frost stepped in to calm the situation: “Sadie stood between them and reminded them that it was a wedding and that they should show some respect.”

“Sienna was in the mood for carrying on the scrap but Rhys persuaded her to call it a night.”
