Saturday was social for Naomi Watts
: The actress, who is expecting her first child
with boyfriend Liev Schreiber, celebrated with a baby shower.
The couple, who according to a source close to them were originally planning to catch that day's Galaxy/Chelsea game (featuring the debut of David Beckham
), instead shifted gears and held an intimate afternoon gathering at their Los Angeles-area home.
Among the approximately 15 guests were Kate Hudson
and actress Carla Gugino, as well as the 39-year-old father-to-be – despite the normally all-female nature of a shower.
Describing her pregnancy
to PEOPLE in May, Watts, 38, said she was "just being relaxed and moving at a much slower pace and enjoying it. I'm just really happy to be pregnant."
Added Schreiber at the time: "She's great. In fact, I've never seen anyone handle a pregnancy so well. She's amazing."
