Queen Latifah's Unusual Endorsement

The singer-rapper-actress has now officially added anti-allergy spokesperson to her resume, appearing in a series of short videos that are part of the brand's interactive YouTube scavenger hunt titled "Parks Unleashed." Also unusual, at first blush: a video game ad from the type of Johnson & Johnson-owned pharmaceutical brand that might normally eschew creative approaches to marketing.

Latifah's clips, rolled out Thursday as the third stage of the campaign, tie in to a choose-your-own-adventure plot line that leads players through an virtual environment rife with pollen and dander, catering to talking dogs and taking detours into minigames like kite flying.
