Aretha Franklin (search) has been hospitalized for an undisclosed ailment and is in stable condition, her publicist said Monday.

The Queen of Soul, who lives in Detroit, was hospitalized Saturday, according to Gwendolyn Quinn, her New York City-based publicist.

Quinn declined to say where the singer had been hospitalized. The publicist said she had no further information about Franklin's illness or how long she would be hospitalized.

The legendary singer turns 62 on Thursday. Last month, she won a Grammy Award for best traditional R&B vocal performance for "Wonderful" from her latest CD, "So Damn Happy."

Franklin, whose soulful voice has made her one of the world's most revered singers, is best known for her signature song "Respect," though she's had countless other hits including "(You Make Me Feel Like) a Natural Woman," "Chain of Fools" and "Freeway of Love."
