Renee Zellweger has relaxed her fitness regime.
The slim star, who usually sticks to a strict macrobiotic diet of fish and vegetables, has reportedly put on 10lbs in recent months and is pleased with her curvier figure.
A source close to the 'Chicago' actress revealed: "Renee's still committed to being in top shape, but she's realised that being too thin isn't attractive.
"She's been obsessed with being skinny for so long, being able to relax is a relief."
Friends of the 41-year-old star, who jogs up to five miles six times a week, thinks boyfriend Bradley Cooper is behind Renee's change in attitude, as he told her he likes women with "a little more meat on their bones".
The insider explained to Now magazine: "She banned dairy a long time ago but Bradley loves ice cream and cheese and Renee's started to join in. Potatoes are back on the menu, too. Bradley's convinced her to loosen up and she's loving it.
"Bradley's been very vocal in telling her he's more attracted to women with a little meat on their bones and Renee's doing her best to oblige him.
"She was so skinny her face looked hollow, but now that it has some fullness back she looks so much younger."
The actress' weight has yo-yoed ever since she first starred in 'Bridget Jones's Diary' in 2001, with Renee having to put on 28lbs to take up the title role.
