The ads, which break next Thursday, bring to life the indulgent, adult nature of the brand by showing the "It girl" in a range of outfits made from some of the ingredients associated with the crisps.
In one version, Palmer-Tomkinson appears in a poppadom hat complete with yoghurt and mint.
The endline reads: "Posh poppadoms from Walkers."
In another of the ads, she is pictured reclining on a giant chilli for the Thai sweet chilli variety. The endline reads: "Posh crisps from Walkers."
The ads support the latest TV campaign. In the ad, the former I'm a Celebrity ... Get Me Out of Here contestant visits a doctor, played by Gary Lineker, to get help in overcoming her addiction to Walkers' Poppadom Bites. During the course of the visit, she strips to reveal stockings and a basque.
Rob Oliver art directed the press executions, which will launch in New Woman and Company magazines before expanding into other titles. They will run until the end of the year.
Media planning and buying is through OMD UK.
Krys Janowski, the Sensations brand manager, said: "We wanted to create a campaign that brought to life the innovative flavours of the Sensations range, and does something very different to historic crisp advertising.
"The resulting ads are stunning, the designs and sets really captured the indulgence and sophistication we wanted to communicate."
Palmer-Tomkinson replaced Victoria Beckham last July as one of the celebrity faces of the Sensations brand to reflect the brand's up-market positioning.
