We love when Sienna goes crazy on someone's ass. Now she is telling the nanny who Jude had an affair with to watch her back. People reports some recent Sienna quotes:

"I'm quite looking forward to the day when our paths will cross, which I know they will," says Miller, 24, of Wright in February's Interview magazine. "She better live in fear."

"I just hope she doesn't run into me in a dark alley."

Yeah, I'd be scared if I was the nanny.
