Miranda Kerr has swapped diamond-encrusted Victoria's Secret bras for something a little more comfortable - a pair of Calvin Klein briefs.
The supermodel today posted a relaxed snap of herself to Instagram where her jeans are pulled down just enough to expose the classic white underwear.
A caption reading "My new Calvin's #mycalvins #ad" accompanied the photo, in which Kerr shows off her toned stomach in a skimpy T-shirt.
It is unknown whether the 30-year-old has signed on as the latest face of the brand or if the snap was purely an audition of sorts to secure a lucrative gig with the designer.
However, Kerr's contracts with David Jones, Mango and Victoria's Secret all recently wrapped up so many are speculating the bombshell is on the lookout for new brand partnerships.
Fellow supermodel Kate Moss and Mark Wahlberg made Calvin Klein one of the hottest labels in the nineties after they fronted an ad campaign wearing the signature white undergarments, with Zoe Saldana and Kellan Lutz lending their bodies to the name more recently.
Kerr's latest snap is the second racy image she has posted in the last few days, with the first showing off even more skin as she posed seductively with nothing but a towel to cover her modesty.The mother indicated it was from a shoot with renowned photographer Mario Testino.
