The 36-year-old actor, who starred in "The Lord of the Rings" and "Pirates of the Caribbean" films, and the 30-year-old supermodel were married in 2010. They have a 2 1/2 year-old son, Flynn.
Bloom is making his Broadway debut as Romeo in director David Leveaux's revival of Shakespeare's "Romeo and Juliet" opposite Condola Rashad, who has back-to-back Tony Award nominations for "Stick Fly" and "The Trip to Bountiful." Reviews have been mostly negative and the show has struggled at the box office.
Kerr, a top Victoria's Secret model, first met Bloom backstage at a lingerie fashion show in New York in 2006. The Australian-born beauty recently worked with chemists to help develop an organic beauty line.
In an interview in September, Bloom said he was excited to be making his American stage debut and taking his career on a new course. He said he was planning to join the Royal Shakespeare Company after college but director Peter Jackson whisked him to New Zealand for "The Lord of the Rings" and then he was off on a movie career — "Black Hawk Down," the "Pirates of the Caribbean" franchise, "Elizabethtown" and "Kingdom of Heaven."
"I feel like this is what I was supposed to be doing or at least part of what I was supposed to be doing. I found myself doing movies — which were wonderful and amazing and I love — I've got a collection of movies at home that my son is going to absolutely drool over when he's the right age," he said. "But for Orlando and for the actor in me, this process is so rewarding and I just feel like I'm going to be a different actor after this. I already feel like a different actor."
