Kate Hudson gave birth to a baby boy on Saturday in Los Angeles, Us Weekly reports.

The actress and Muse rocker fiance Matthew Bellamy are parents together for the first time; publicly dating since early 2010, Hudson told InStyle in April that a baby wasn't necessarily part of the plan -- not that she was complaining when she found out.

"Well, it wasn't like we didn't know what we were doing," she said. "There were no ovulation kits involved. We were tempting fate, and it worked... I didn't think I was going to have another kid until I was maybe 33 - that was in the back of my mind before I met Matthew. But we were so in love when it happened, it was just so exciting for both of us."

Hudson has a child, 7-year old son Ryder, from her previous marriage to Black Crowes rocker Chris Robinson. Hudson announced the pregnancy in January.
