The 28-year-old actress, who is set to make her debut in a West End play 'Speed-the-Plow' later this year, has been hitting gym more than ever, reported Conatctmusic.
"Now she's based in London she doesn't have many friends here, so I'm with her basically every day. We work out, she's a fitness freak!" her blogger-friend Vas J Morgan said.
The actress, who had court-ordered rehabilitation treatment last year, is now focusing on work and fitness and hence avoids drinking.
"She's focusing on work and trying to rid herself of the demons that follow her in New York and LA," Morgan said.
