Australian model Miranda Kerr has posted a topless photograph of herself online, and she has censored her modesty on her own.

She posted the photograph, in which she is caught on camera making a splash in the sea, wearing only a pair of bikini bottoms, on Intagram, reports thesun.co.uk.

Kerr appears to be using her hands to partially protect her modesty.

She tweeted the pic, writing, "You're the best @chriscolls @koraorganicsbymk #purenature #freespirit"

She has been a busy bee of late, travelling the globe on work assignments and high-profile social occasions.

In February, she graced the Oscars red carpet with husband Orlando Bloom, further quashing rumours their marriage is on the rocks.
