Miranda Kerr shared this racy image with fans on InstragramInstagram

After Orlando Bloom stepped out with rumoured love interest Nora Arnezeder, Miranda Kerr has reminded her estranged husband what he's missing by sharing a topless picture of herself on Instragram.

The former Victoria's Secrets beauty, who split from Bloom in October 2012, is no stranger to stripping down but the racy picture proves she's still a hot commodity.

In the black and white image, the 30-year-old Australian supermodel can be seen lying on some comfortable bedding while her tousled locks fall to one side of her face.

She captioned the picture from a recent photoshoot: "Thank you @wmag @mertalas @macpiggott @edward_enninful."

It follows mounting speculation that Bloom has finally moved on with 24-year-old Arnezeder after the pair were spotted at Los Angeles speakeasy the Roger Room.

The outing was the first time The Lord of The Rings Star has been seen with another woman after calling time on his three-year marriage with Kerr.

Kerr uploaded her risqué image the same day she was named the new face of H&M's Spring and Summer 2014 campaign.

The high-street retailer announced the news by posting a video featuring the mother-of-one on its Instagram page.

"Hi H&M followers, I'm Miranda Kerr and I'm the new face of H&M's spring campaign," Kerr said in the short clip. "Stay tuned for more."
