Emily Blunt threw herself a baby shower, surrounded by just a few close friends at her home on Saturday.
"It was an intimate shower for a few close girlfriends," said the source. "It was very small and low key."
Guests said pink balloons decorated the Hollywood Hills home, where snacks and water were on hand for a pregnancy-friendly time.
Blunt, 30, is expecting her first child with husband John Krasinski this winter. They were married in 2010 in Italy.
