Why so much bad blood between these two? Sometimes I wonder if any of it's real of if the media is just inventing a Kate Moss/Sienna Miller rivalry to keep us entertained. That being said, I've learned that the saying, "Where there's smoke, there's fire," is often true in this biz.

Anyways, Sienna reportedly broke up with Rhys Ifans by phone and now she won't answer his calls. He's drowning his sorry in alcohol and as one of his closest friends, Kate is extremely upset about the way the breakup was handled.

"Rhys is probably Kate's best male friend. In fact, she's as close to him as a sister and she's very protective of him because she knows his vulnerabilities. Kate's not someone you'd want on the opposing team. She's a formidable woman and very loyal when it comes to her friends."

She's gone so far as to let him live with her for a while!

"Kate has taken Rhys in and told him he can stay at her place for as long as he wants. He's in a bad way and she's really angry at Sienna, even though she knew she'd never stay with Rhys."

If these two had a show down, who do you think would win the battle of skinny blonds? I'm just asking. :)
