Sheryl Crow has launched a sarcastic attack on the world's rehabbing celebrities by suggesting she needs to check into a treatment clinic to boost her career.

The singer/songwriter, who has battled depression for years, joked about recording a duet with troubled British singer Amy Winehouse during a show at London's Scala venue on February 19 - before poking fun at stars in rehab.

Crow told fans, "I want to collaborate with Amy because she's really hot and cool right now. I know one song, "Rehab," was very popular, particularly because a lot of young people are in rehab. In fact, I'm thinking about going. It looks like loads of fun and I know my career will benefit from it."
