On Monday -- the morning after he performed his 1,000th Las Vegas concert -- 68-year-old pop legend Barry Manilow entered a Los Angeles hospital to repair torn abductor muscles and removal of bursas in both hips. According to a Tweet posted on his Twitter account, the surgery went well and the singer is recovering. He is seen in this file photo from July 12, 2011. (Kevin Winter/Tonight Show/Getty Images)
