Amy Adams says she isn't due until spring - but she can't bear to wait that long to find out the sex of the baby.

"We will probably find out," she tells Entertainment Tonight. "I thought about waiting, but that is not my personality. I am impatient. It is not about planning a nursery; it is more about I want to know. I want to relate in that way." confirmed Friday that the 35-year-old actress -- who returns to the big screen next month in comedy Leap Year -- and fiancé Darren Legallo are expecting their first child together.

The two, who first met in acting class in 2001, became engaged in July 2008.
