The Miranda Kerr wedding to Orlando Bloom took us all by surprise but now the Lord of The Rings actor and his Victoria's Secret supermodel wife are back from their Caribbean honeymoon and showing off their gold wedding rings!

They were spotted in the Miami International Airport on their way to LAX.    Kerr now has some major bling on her fingers.  The gold wedding ring works well with her other diamond—an oval diamond set on a white gold or platinum band, the Diamond Information Center reports to US Weekly magazine.  The Center estimates it to be 3 to 4 carats and upwards of $65,000 while Modelinia.com believes it could be 5 carats and as much as $450,000.

The British actor and his model wife got married only a month after they announced they were engaged.  At the time, Kerr was spotted attending a church in Los Angeles with her mother with the engagement ring on her finger.
Both Bloom and Kerr have been quiet about their relationship, which has lasted since 2007 when a friend introduced them. 

Previously, Bloom had been in a relationship with Blue Crush actress Kate Bosworth.

The world only found out the celebrity couple was married because Kerr released a statement after cancelling an appearance with department store David Jones where she said Jones was gracious enough to release her to celebrate an intimate ceremony.  By then the model and her Lord of The Rings beau were already on their honeymoon.
