Dr. Phil, move over. There's a new advocate for tough love on the circuit: Natalie Cole.

The multiple Grammy winner - her first win, in 1975, was for best new artist of the year - told PEOPLE at Sunday's Warner Music Group post-Grammy party that she took a dim view of Amy Winehouse's awards sweep at the Grammy ceremony earlier in the evening.

"I don't think she should have won. I think it sends a bad message to our young people who are trying to get into this business, the ones who are trying to do it right and really trying to keep themselves together," said Cole, 58. "We have to stop rewarding bad behavior."

Of Winehouse, 24, Cole says: "I'm sorry. I think the girl is talented, gifted, but it's not right for her to be able to have her cake and eat it too. She needs to get herself together."
