Manuela Testolini is the second ex-wife of the late Prince.
The singer, who was born Prince Rogers Nelson, performed a show in Atlanta last Thursday prior to becoming sick, and appeared at a dance party in Minnesota on Saturday to let his fans know he was doing better after his sudden hospitalization.
The singer seemed to live a remarkably healthy life, having been a strict vegan for over a decade and becoming one of Jehovah's Witnesses in 2001, a faith that largely prohibits the consumption of alcohol.
On Wednesday the 47-year-old hit maker announced to Us Weekly that he and his spouse have welcomed their second daughter, who they named Amoura Luna.
He already has a 23-year-old daughter India from a previous relationship and another girl, Lucia Bella, aged two, with Manuela.
Manuela Testolini has announced that she is building a school in memory of her late ex-husband Prince.
