(Cover) - EN Showbiz - Miranda Kerr has slammed rumours her marriage is on the rocks.

The Australian model and her husband Orlando Bloom have 18-month-old son Flynn together and have been married for two years.

Over the weekend a magazine claimed their relationship was in trouble after both stars were spotted without their wedding rings. Miranda has denied the claims via her manager.

"There is absolutely no truth in the headline or story," Annie Kelly told the Australian Daily Telegraph.

It was suggested Miranda and Orlando have been concentrating on their careers lately and neglecting their romance.

The 29-year-old model was seen walking around New York City looking relaxed and happy, but without her band on. A friend of the star told Famous magazine Miranda's marriage might have "slipped between the cracks".

Miranda has previously spoken about how important marriage is to her. She even revealed her grandmother had advised her not to "let herself go" during her pregnancy, as it was vital Orlando was still attracted to her.

She has also praised her 35-year-old spouse's parenting skills and said she is happiest with Orlando and Flynn.

"We love it - now we argue about who's changing the diaper!" she laughed. (C) Cover Media
