The pair are part of the new #MyCalvins campaign on Instagram. The brand signed up models, musicians and fashion bloggers to get involved and flash their underwear for the camera.
Other celebs showing off their undies as part of the campaign include singers Trey Songz and Iggy Azalea and shoe designer Chiara Ferragni.
Model Lara Stone also got involved and shared this snap with the caption: "Nothing comes between me and #MyCalvins @calvinklein"
Of course the campaign has had a chain reaction and everyone is now posing in their Calvins and sharing the snaps.
More Miranda Kerr? Well, of course.
