Drew Barrymore and fianc Will Kopelman enjoyed a joint celebration this weekend.

The couple have not formally announced they are expecting their first baby but the actress's growing baby bump speaks for itself and they are indeed planning their wedding.

People magazine reports that the loved up couple were guests of honour at an intimate gathering in Los Angeles. It was hosted by producer Leonard Goldberg and his wife Wendy. Leonard produced the Charlie's Angels movies with Drew.

"[They were] just enjoying talking about wedding plans and are excited for married life," a friend told the publication.

"[Drew] is excited about the wedding, but very laid back. She is definitely not a bridezilla."

Meanwhile, Us Weekly reports that "everyone was doting on pregnant Drew and asking her how she is feeling."

"She is so thrilled to be expecting, and also really excited about the wedding," the source said.

"Drew will be an amazing mom. She's seriously the coolest person in the world. Very generous and doting."
