Chaka Khan is in rehab and was motivated to seek treatment after Prince's death.

The 63-year-old Grammy-winning R&B and funk singer, known for songs such as "Tell Me Something Good," a cover of Prince's "I Feel For You," and "I'm Every Woman" (made more famous by the late Whitney Houston), and her sister Yvonne Stevens, aka Taka Boom, recently entered a rehabilitation program to treat their addictions to prescription drugs, multiple outlets reported Sunday.

Khan reportedly said she has been battling an addiction to the same medication that led to Prince's death and that his passing had spurred her decision to seek treatment. Prince died from an overdose of fentanyl, an opioid painkiller at age 57 at his Paisley Park studios in April.

A rep for the singer said Khan has struggled with prescription pain medication dependence and has "voluntarily entered" a treatment program "to get healthy and stay that way."

"Chaka Khan has entered an addiction rehabilitation and aftercare program which will cause her to postpone all dates scheduled for the month of July," her rep said in a statement with E! News. "Chaka has struggled with a dependence on prescription pain medications and has voluntarily entered the program to get healthy and stay that way. As part of the ongoing outpatient treatment the doctors have urged her to resume recording mid-July and all performances beginning August 1st and onward."
