Miller ended her engagement to JUDE LAW in July (05) after he admitted sleeping with his former children's nanny.
She forgave him, but has made it quite clear Wright would be in trouble if they ever met.
The actress says, "I am quite looking forward to the days our paths will cross, which I know they will... She better live in fear, I just hope she doesn't run into me in a dark alley."
A friend close to Wright says, "Daisy can't believe Sienna has spoken out like this. She has accepted Jude back and put all the blame on Daisy.
"It takes two people to have an affair.
"It's pretty nasty and frightening and Daisy shouldn't accept it. We have told her to go to the police. Sienna just needs to forget about it and stop raking over old coals. Making childish threats achieves absolutely nothing."
