Demi Lovato is "happy" to be at home with her family after completing her stint in rehab.

The 18-year-old singer-and-actress left an unnamed Clinic in Illinois, US, on Friday (28.01.11) after being treated for "emotional and physical issues" and returned to her family home in Los Angeles where sources told the New York Post's page six she will continue to see doctors for her problems.

A representative for the star confirmed, "Demi is happy to be back home and near her family again."

Demi entered rehab voluntarily at the beginning of November last year after an incident in which she punched a backing dancer, but the 'Sonny with a Chance' star is said to be determined to undertake a solo tour this year.

A new song by the Disney actress called 'Shut Up and Love Me' has also leaked online, leading fans to believe she is ready to step back into the spotlight.

Demi wrote on Facebook earlier this month: "I want to make sure my fans know how thankful I am for all their love, support and prayers. Thank you for standing beside me."
