A-list actress Kate Hudson was not prepared for this fan frenzy at Nobu in Malibu this weekend.

Kate and her kid went out for a nice/quiet dinner at the famous sushi joint when she realized she was at Kylie's 18th pre B-Day dinner party. And when there's Caitlyn, Kim and the KUWTK crew. The fan/pap frenzy gets a bit crazy.

Not too sure if Kate was a part of the festivities but she was none too pleased with people shining a light in her face while trying to drive away.
