Former Mis-Teeq star Alesha Harvey has warned Lily Allen to stop criticising other pop stars.

The singer has praised Lily's debut single Smile but believes that people could soon turn against the 21-year-old if she carries on making disrespectful comments.

"I like Lily's song but I don't like hearing her putting down other artists," she told the Daily Star. "We should all support each other. It's wrong to do it as it can mislead the public."

Lily has recently slammed stars such as Madonna, Pete Doherty, James Blunt and Kooks singer Luke Pritchard.

Alesha's debut solo single Lipstick is released today.
