This celeb social media campaign is way tastier than dumping ice on your head – and for a just as important cause.

Yolanda Foster is asking her famous friends to help spread awareness of Lyme disease by posting Instagram photos of them sucking on – you guessed it – actual limes.

“It takes a village, please pass it on,” Foster, 51, captioned a picture of her and her husband, music mogul David Foster, biting into the fruit Sunday.

Real Housewives of Beverly Hills costars Lisa Rinna, Kyle Richards and Lisa Vanderpump have already accepted the #LymeDiseaseChallenge.

Foster was diagnosed with the chronic disease in 2012 and has said it’s made reading and writing incredibly difficult. The former model has been open about her battle, supporting singer Avril Lavigne when she revealed her owns struggles with Lyme.

“I took Avril under my wing when she first got sick and shared all I know,” Foster said in an interview with Bravo earlier this month. “I am so proud of her for going public and helping us bring awareness to this debilitating disease.”
