BURBANK, Calif. (AP) - We now know why Drew Barrymore named her daughter Olive and it wasn't because she the starring voice in the movie "Olive, The Other Reindeer."

Barrymore told Ellen DeGeneres on her talk show that she was reading a baby book when she was three months pregnant and saw that a baby at that age is the size of an olive.

She says "that was it" and she "never looked back." Olive is ten months old now.

She's the first baby for Barrymore and her husband Wil Kopelman.
