The Australian supermodel, who has a two-year-old son, Flynn, with her husband of three years, stepped out to support the British actor as he made his Broadway debut in a new adaption of 'Romeo and Juliet' on Saturday night (24.08.13).
The 30-year-old beauty shared a photo of Orlando's name in lights outside the event on Twitter with the caption: ''Go Romeo! So proud of you (heart)''
Miranda was in the audience for a special preview of the new production at the Richard Rogers Theatre, which will officially open on September 19 and run until November 24.
The brunette beauty relocated to New York earlier this year so Orlando, who starred in the Hollywood franchise 'Pirates of the Caribbean,' could prepare for the play.
The couple have been plagued by rumours of a split over the past year but Miranda recently dismissed the constant speculation.
She told Australian magazine The Sunday Style last weekend: ''Yeah, I don't even know where some of these stories come from. It's quite comical. It is what it is. It's all part of the job, I guess. People say what they want. At the end of the day, we don't really need to prove anything to anyone.''
