Katy Perry has reportedly signed up as the new face of an acne cream. The 'Waking Up In Vegas' star inked a deal worth around $4m (£2.4m) to endorse Proactiv, following previous campaign models Jessica Simpson and Jennifer Love Hewitt.

Perry is to film a run of TV adverts in which she discusses her own acne issues.

The 25-year-old is quoted as saying, "I got acne at the start of my career. It was stressful. I have acne scars which I'm self-conscious about." Proactiv spokesman Ben Van de Bunt added: "We are paying people consistent with what we have done in the past - millions of dollars."
