Turns out that the girl that Kate Hudson thought she was having came out with a little penis attached!

Yesterday, July 9th, Matthew Bellamy and Kate Hudson welcomed a son into their family. The healthy baby boy was born in Los Angeles. No word on his name, or how much he weighs.

Kate, 32, and Matthew, 33, started dating last year and announced their engagement in April. In January of this year the couple announced that they were expecting a baby together.

This is Matthew's first child. Kate already has a son from her marriage to Black Crowes rocker Chris Robinson, 7 1/2-year old Ryder.

UPDATE: Wednesday Matthew Bellamy revealed his son's name in a tweet. Kate and Matthew have decided to name him Bingham 'Bing' Hawn Bellamy.
