The three-month campaign, which begins this week, will see a show created specifically for the underwear firm, airing on Thursday evenings on Emap's Heat radio.
Taking content from Heat magazine, this advertiser funded programme will provide listeners with tips on how to achieve the hottest look while offering the chance to win a weekend in Paris.
Wonderbra will also sponsor Heat's Studio 84 show on Friday and Saturday evenings, aimed at young women getting ready to go out.
The on-air activity will be supported in print with Wonderbra branded advertorials in Heat, as well as an extensive online campaign.
Rob Tomalin, head of strategy at the publisher's cross-media sales team, Emap2, said: "This shows how our full-service structure creates and delivers genuinely creative cross-platform solutions."
