Sarah Palin and her family are calling for prayers for an unlikely ally — the ailing comedienne Joan Rivers.

The former GOP vice presidential candidate posted a link on her Facebook page Friday directing fans to a post by her 23-year-old daughter, Bristol.

{mosads}“You have already probably heard that Joan Rivers is in a medically induced coma after she stopped breathing during her vocal chord surgery,” wrote Bristol Palin. Rivers’s daughter, Melissa, said Friday her mother’s condition “remains serious” but she is “resting comfortably” at a New York hospital after being admitted Thursday. She reportedly suffered cardiac and respiratory arrest during a procedure on her throat.

Rivers, 81, and Palin both appeared on ABC’s “Wife Swap” last year.

“As you may remember, I developed a soft spot in my heart for her when we were on Wife Swap together,” Palin writes. “Please pray for her healing and for her family during this awful time.  :(“

Sarah Palin also recently cited Rivers, along with SiriusXM host Howard Stern, on her online subscription-only channel. The former Alaska governor called the pair “unlikely source[s] of foreign policy wisdom,” before commending them for their vocal support of Israel.

“Even though Joan, she’s a Hollywood style critic, well no doubt she’s repulsed by my style — or lack thereof — but I declare that she is right and I admire her so much for speaking up for truth,” Palin said in a video commentary.
