The reason? Wood tweeted Tuesday that the talk-show host's 2008 documentary, The Business of Being Born, helped her make the decision to have a natural home birth.
"I have to say thank you @RickiLake for your inspiring documentary…I never knew I had a choice when it came to labor. It taught me so much & aided my decision in having a natural home birth which my son & I are now forever grateful for," she wrote on the social networking site, just one day after announcing her happy baby news.
Lake, a mom of two, tweeted the actress back, writing, "You are so welcome. Overjoyed to hear you had a positive birth experience & a beautiful son! :) #BOBB xo"
And Wood, 25, is completely in love with that beautiful son! She tweeted a link to a scene in Raising Arizona—where Holly Hunter hilariously and dramaticly sobs over how much she loves a baby—adding cutely, "This pretty much sums up my feelings today. My heart is ready to burst!"
