The 'Yes Man' star has announced she and husband Scott Stuber have welcomed their second child, Scarlett May.

Writing on her website, the 41-year-old actress captioned a picture of the little tot with the words: "We welcome Scarlett May Stuber into our family. Our hearts are bigger with you here."

Meanwhile, Molly - who also has two-year-old Brooks - previously revealed she had given herself gastritis after eating too many citrus fruits, which had caused some "really painful" side effects.

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."

And in order to stay in shape, the blonde beauty has been doing lots of exercise to keep her weight gain during the pregnancy to a minimum.

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."
