Sienna Miller feuds with Jude Law`s ex on Twitter

London: Hollywood beauty Sienna Miller fell out with her fiancé Jude Law`s ex-wife Sadie Frost after the actress gave her step daughter a hair cut and the fight spilled over to Twitter. Frost who has three children with the `Alfie` star had left them in Miller`s care when she went to the Isle of Wight festival with best friend, model Kate Moss.

But when she came back, she found that the actress had cut off the hair of her her nine-year-old daughter Iris. Miller, 28, had cut off Iris`s long hair and given her a boyish elfin cut, reported Sun online. Frost, 42, was so annoyed that she ranted on Twitter, writing, "I think ya should get ya own child and then cut their hair!" "Sadie had a great time at the festival but it was all forgotten when she saw Iris`s hair. It`s not that the style doesn`t look nice but that it was done without her permission," said a source close to Frost, a former model. "I`m sure Sienna was just trying to be nice. But Sadie doesn`t want Sienna playing mum to her kids," added the source. PTI
