Actress Mischa Barton turns to God following her arrest for drink and drug offences

The former O.C. star was seen leaving a service at The Good Shepherd Catholic Church in Beverly Hills on Sunday.

An onlooker told gossip website TMZ.com: "Mischa came out of the church looking very pious, wearing a white, virginal dress. She was carrying a church brochure."

The 21-year-old was arrested on suspicion of drink-driving and drugs possession in Los Angeles last week and spent the night in a police cell.

Mischa was arrested and handcuffed after she was pulled over while driving her white Range Rover in West Hollywood.

The LA County Sheriff's Department revealed she was seen "straddling two lanes of traffic and failed to signal when making a turn".

She was held in police custody for seven hours on $10,000 (£5,000) bail, until she was finally released.

Mischa was born in London, to her Irish photographer mother, Nuala and English father, Paul Marsden Barton, a stockbroker.

But the family, including her two sisters Hania and Zoe, moved to New York when she was four.

Younger sister Hania, 19, checked into a rehabilitation facility for addiction to prescription painkillers last year.
