Megan Fox and her husband Austin Green kept the their baby boy's birth a secret for more than two weeks, which is crazy long when it comes to Hollywood. And how did they do that? With a little help from Reese Witherspoon! “We got really lucky and I’ve been wanting to send Reese Witherspoon flowers for like a month and a half now. Because she actually gave birth the day before us in Santa Monica and we were lucky enough to go in at like 2:30 in the morning to the hospital and nobody knew", Austin recently said. Woah, good luck there, huh?
