Demi Lovato is doing well in rehab: Sterling Knight

London: Teenage actress Demi Lovato`s "Sonny with a chance" co-star Sterling Knight says she is in "good spirits" and recovering well in rehab.

The actor recently reached out to Lovato, who entered a rehabilitation centre last month to seek professional help for undisclosed "emotional and physical issues". "She`s doing well. She`s in good spirits. I didn`t want to bother her too much because I want her to get her rest. I know she`s been overworked for a long time. I`m hoping she stays strong and gets through it," contactmusic.com quoted Knight as saying. "You`d rather nip it in the bud sooner than later. I know she`s been real busy - almost entirely too busy for any human being, let alone a 17-year-old girl. It`s nice that she`s handling her stuff." IANS
