Legendary singer Connie Francis has been hospitalized after she experienced “extreme pain,” she told fans on Facebook.

The 87-year-old pop star, whose hits “Everybody’s Somebody’s Fool” and “My Heart Has a Mind of Its Own” charted in the 1960s, was rushed to a Florida hospital’s intensive care unit last Wednesday.

“I am back in hospital where I have been undergoing tests and checks to determine the cause(s) of the extreme pain I have been experiencing,” Francis said in a Facebook post on July 2.

She’s since been moved out of ICU to a private room, after undergoing testing, she said in another Facebook post on Thursday. On Friday, she said she was “feeling much better.”

She had to miss her July 4 show because of her hospitalization.

Francis’ 1962 hit “Pretty Little Baby” went viral on TikTok earlier this year, with more than 3 million lip synch videos, according to Billboard.
