Molly Sims's cravings have painful side effects

Molly Sims has given herself gastritis by eating too many citrus fruits.

The 41-year-old 'Yes Man' actress, who is set to give birth to her second child imminently with husband Scott Stuber, admits her healthy cravings have caused some "really painful" side effects, including inflammation of the lining of her stomach.

She said: "With my first pregnancy it was apples, but this time around I've had so many mandarin oranges and grapefruits to the point where I got gastritis. It's really painful, but I can't stop! Normally I don't even drink OJ, but this morning I drank it straight from the jug. It's so weird."

The former Sports Illustrated model, who is expecting a baby girl, says she has gained less weight this time around after putting on 80 pounds while pregnant with son Brooks, two.

She told The Bump magazine: "With baby number two, I've only gained about half of that and I've felt much more energetic."

But the blonde beauty admits she has done a lot less exercise.

She explained: "I did a lot less cardio and a lot more Pilates. I still did Tracy Anderson and spinning, but I took it much easier. My body just didn't feel like I needed it, especially in the middle months, and I didn't want to push it as hard. Some days you have energy, and some days you feel like you've been hit by a bus. It's so important to really listen to what your body is telling you and go with it."
