Nicky Hilton Rothschild enjoyed a lavish baby shower on Tuesday (21.11.17) - but although she shared photos of her lavish baby shower on her Instagram account she did not reveal the sex of her unborn tot.

The 34-year-old socialite is expecting her second baby with husband of two years James Rothschild, a younger sibling for their 16-month-old daughter Lily.

Nicky's baby shower was a sophisticated tea party with guests served an array of delicious icing covered cakes, macaroons and biscuits, and the blossoming blonde posted an array of pictures taken at her mother Kathy Hilton's Bel Air mansion, where the party was hosted, along with the caption, ''A baby is brewing''.

Mother-to-be Nicky looked radiant in a swirling pattern dress adorned with blue, pink and yellow flowers, and guests included her older sister Paris, 36, and their brother Barron's fiancée Tessa Von Walderdorff.

And while it was a girls only event, Paris' boyfriend Chris Zylka was spotted gatecrashing the bash in her Snapchat posts.

Nicky is reportedly due to give birth around Christmas time and she previously admitted she feels ''very prepared'' for motherhood the second time around.

She also spilled that Lily can't wait to be a big sister.

She said: ''I know what to expect. I'm good, I'm ready.

''I think Lily will be really sweet. She doesn't have a jealous bone in her body. When I hold other babies, she doesn't care. She's very sweet. I try and explain it, [but] she's too young. I did get her a doll that she gives a bottle and takes in the bath with her.''
