Jaime Pressly has announced that she is four months pregnant. On a taping of the Tonight Show to air Wednesday night, Pressly said she initially denied the rumors that she was expecting because she wanted to get past the first trimester. "I lied and lied and lied!" she said. The My Name is Earl actress and her fiance, DJ Eric Cubiche, hope to find out the sex of the child next Monday. "I live off Tylenol," Pressly said of the pregnancy so far. "The mood swings you can't do anything about. You want to stab people and you don't know why! I'm still tired. You wake up sleepy... I'm healthy, the baby's healthy, we're good." And when asked when she'll tie the knot? "I'm not even thinking of planning a wedding right now," Pressly admitted.
