The Jennifer's Body star opened up about her issues in 2010, and admitted she was so terrified of germs that she couldn't bear to eat out at restaurants.
But after the arrival of her firstborn Noah, the star reveals her anxieties about bacteria have eased up.
She tells Britain's Marie Claire magazine, ""I think (husband) Brian (Austin Green) was waiting to see what I would do (during the birth), because, you know, when they come out they are covered in all kinds of stuff. I took him right on my chest and, from that moment, nothing he does freaks me out. I don't want to give him a complex. (The anxiety) has been significantly better since he was born. I would say, like, 80 per cent better. Which is nice.""
