British rocker Pete Doherty has checked into rehab, a source confirms to PEOPLE.
The Babyshambles frontman is staying in the $600-per-day Clouds House, near Salisbury, Wiltshire, about two-and-a-half hours southwest of London.
Doherty, who recently used the UK's Daily Mirror to profess his love
for on-off girlfriend Kate Moss
, spent part of Friday in group therapy.
At the 38-bed facility, the singer is expected to do chores – called "Therapeutic Duties" – including vacuuming the lounge in the shared house or setting the table for dinner. He can also take part in Friday night sing-alongs with a band called Mustard Seed, who put "recovery lyrics to popular music," according to the center's Web site.
A friend tells PEOPLE: "He really needs help, and we're grateful he's getting it."
Doherty has battled drug addiction for years and has had numerous run-ins with police for drug offenses. In July he admitted in court
to possessing quantities of crack cocaine, heroin, cannabis and ketamine as well as to two driving infractions.
Earlier this week, the 28-year-old singer was arrested on suspicion of carrying drugs after police stopped his car in East London. He escaped jail on a technicality: Police failed to take him to a courthouse in the required time limit.
He has previously received treatment
at The Priory.
