An onlooker said: "There was a lot of laughing and even some speeches. Nicole and Joel were nestled in the centre of the big group and looked as happy as they could be to be celebrating with their friends. They were beaming in the soft terrace lighting."

The highlight of the evening was when Joel was presented with a huge birthday cake, accompanied by a rousing rendition of 'Happy Birthday'.

The source added: "It was so big I'm surprised it didn't set off the fire alarms."

Although they were not members iof the party group, Sharon Stone and Drew Barrymore were both spotted dining at the Sunset Tower on the same night.

Nicole, 27, and Joel recently announced they are expecting their second child together. They already have a 14-month-old daughter Harlow.
