The 'Devil Wears Prada' star was joined by a bunch of close pals - including Matthew McConaughey's wife Camila Alves - at the celebration, as she prepares for the birth of her first child.

A source said: "Anne was one of the first people to arrive. She looked relaxed and happy to be there.

"There was a lot of chatter and laughter throughout the afternoon. Many times there was giggling and clapping because all of the ladies were having so much fun."

Later on in the afternoon, Anne's husband Adam Shulman - who she tied the knot with in 2012 - appeared alongside the mother-to-be's family and their arrival was well received.

An insider added: "They seemed excited to get inside the party. At the end of the shower, they helped pack up all the gifts. He's been helping Anne shop a lot for the baby. They've been ordering a bunch online too. They are as happy as clams."

Anne and Adam have yet to confirm the gender of their baby but speculation it is a girl was only fuelled by Camila, when she arrived at the party carrying a basket of gifts with the letter 'G' printed on it.

A source shared to Us Weekly magazine: "The colours of the presents were mostly neutral, with the exception of Camila's."
