As well as her husband Joel Madden and dad Lionel Richie, other celebs included on the guest list were Kate Hudson, Cameron Diaz, Jessica Alba and Ellen Pompeo.

Of course, they all documented the fun on Instagram.

Fur, gold and big hair was the style for most on the night.

Disco's dead.

But while Kate Hudson was seen channelling her Almost Famous character Penny Lane, Cameron Diaz didn't seem to be as into the retro theme.

The star opted for a more understated look in all black.

Happy birthday gorgeous! 🎂😘🎂 @nicolerichie #DiscoNight 💃
