Christina Applegate Talks Pregnancy Diet, Weight Gain, Mood Swings (VIDEO)

Christina Applegate visited 'Lopez Tonight' on Thursday, where she talked about her pregnancy cravings and weight gain. George asked her if her friends warned her about what being pregnant would feel like.

"They tell you it's so fantastic. My friend was like, 'Oh don't worry, I gained 15 pounds," she said. "I'm like, '[expletive!]'"

She also talked about her pregnancy diet - which was healthy, she said, until she arrived on the 'Lopez Tonight' set.

"I crave food! I don't care what it is!" she said. "I came here and within 30 seconds I had a Sprinkles cupcake and a bunch of fried cheese. I eat macrobiotics for the most part, and I eat really well ... until I came here."

Earlier this week, Christina appeared on 'The Late Show,' where she said pregnancy has made her lose her filter. She popped a fuse when a security guard got after her for an illegal parking job.

"I was just like, Shhhhh! Shhhhh! It is too hot out to be a douchebag, okay?!" she said. "What's wrong with me? I was like, 'Who am I right now?! That's a horrible thing to say to somebody!'"
