Pregnant Megan Fox and her husband, Brian Austin Green, grabbed lunch in LA together yesterday with his son, Kassius. They're hanging on the West Coast as they await the arrival of their first child together. The baby will make Kassius, whose mom is Brian's ex Vanessa Marcil, a big brother. Megan wore a bikini in a photo shoot with Brian to confirm rumors about her pregnancy back in June. She's among the many pregnant celebrities at the moment, including Gisele Bundchen, Camila Alves, and Reese Witherspoon. The nonstop family time may have to cease for a minute this Winter for Megan, who's due to help promote her movie This Is 40 ahead of its December release.
