Singer Chaka Khan enters rehab

(CNN)Grammy award winning R&B singer Chaka Khan is canceling her July performances in order to focus on her health, according to her website.

The 63-year-old singer will enter into a drug rehabilitation program.
"Chaka has struggled with a dependence on prescription pain medications and has voluntarily entered the program to get healthy and stay that way," a message to fans on Khan's website said Sunday.
    She became a household name and was propelled to stardom from the song "I Feel For You," written and first performed by Prince.
    Khan is expected to perform in Atlanta; Atlantic City, New Jersey; Grand Prairie, Texas; and St. Louis starting August 5.
    She should be back with a microphone in her hands very soon, as "doctors have urged her to resume recording mid-July and commence all performances beginning August 1st and onward," the statement said.
    CNN has reached out to Khan's publicist for more information.
