Hollywood beauty Mischa Barton has hired a personal trainer in a bid to clean up her act following her drink-driving conviction.
The 22-year-old former The O.C. star was recently pictured relaxing on a beach in Los Angeles - but she has now hired a trainer to raise her fitness levels.
She says: "I never had a workout regime, but I have now hired a personal trainer because I feel my energy level is better when I work out."
Last week, Barton was sentenced to three years unsupervised probation after pleading no contest to charges of DUI, possession of marijuana and driving without a licence in February, following an arrest in West Hollywood in December.
