A rep for Law has tamped down recent rumors that Law and Miller have restarted their romance now that they're both in the Big Apple to perform on Broadway (he in Hamlet, she in After Miss Julie).
"Jude and Sienna are just friends," the rep tells Glamour.com, "and are seeing each other socially occasionally as they are both on Broadway, performing just one block apart."
The pair — once engaged before Law's affair with his children's nanny came to light — broke up for good in 2006.
Law, 36, recently became a father for the fourth time when former girlfriend Samantha Burke, 22, gave birth to Sophia Sept. 22.
Miller, 27, was most recently involved with Balthazar Getty — who is married with four children. The G.I. Joe actress admitted to British GQ that the adulterous affair "probably looked awful . . . I probably seem like not a particular nice person, not a girl's girl."
