Jude Law has shot down rumors he's secretly dating ex-girlfriend Sienna Miller while the pair is starring in rival Broadway productions.

The actors split in 2006 after Law was caught cheating with a nanny who cared for his kids with ex-wife Sadie Frost. They were reunited this month when they both landed roles in New York stage shows; Law in Hamlet and Miller in After Miss Julie.

Miller has been spotted sneaking into a matinee performance of Hamlet, and the pair has been seen enjoying nights out together - prompting rumors the romance is back on.

Law admits they're in touch, but insists the relationship is purely platonic.

His representative tells Glamour.com, "Jude and Sienna are just friends and are seeing each other socially occasionally as they are both on Broadway, performing just one block apart."
