Paris posted a photo of the British model sporting a large red lipstick mark on the side of her cheek.
Cara modelled the prominent mark which appeared to be a sign of Paris’ love.
The catwalk star seemed to exhale smoke in the candid snap as she posed side on wearing a leather jacket.
Cara, 25, also opted to wear a pair of sunglasses to protect her eyes from the sun.
In other snaps posted to Michael Jackson’s daughter’s Instagram page, Paris, 20, and Cara could be seen larking around with filters.
The two were seen with rabbit ears as they posed to the camera, enjoying each other’s company.
On the same day, the pair were spotted wearing matching attire in a photo uploaded by CR fashion Book editor, Carine Roitfeld.
Paris and Cara sported similar vintage tops which featured large marijuana leaf graphics.
They also both wore patterned headbands for their outing.
In March, Paris and Cara were caught enjoying a smooch while out with Paris’ godfather Macaulay Culkin and his girlfriend Brenda Song.
