Kate Winslet's the proud mom of a healthy baby boy!

The actress welcomed her first child with husband Virgin Galactic businessman Ned Rocknroll on Saturday. Kate -- who tied the knot with Rocknroll last December -- will definitely be having a very happy holiday season and anniversary!

A rep for the 38-year-old tells toofab, Kate gave birth on "Saturday, Dec. 7 at an NHS Hospital in Sussex County, UK," and that the "mother and baby are doing great."

The "Revolutionary Road" actress has a daughter Mia, 12, with ex-husband Jim Threapleton, and son Joe, 9, with ex-husband Sam Mendes.
