AceShowbiz - Celebrities flocked Goya Studios in Hollywood, Los Angeles over the weekend to attend the 2018 Just Jared Halloween Party. Among those who showed up in costumes were Ireland Baldwin and her cousin Alaia Baldwin as well as sisters Rumer and Scout Willis.

The model daughter of Alec Baldwin definitely turned heads at the event, getting her body covered in blood as she brought along an axe with her, as if she just killed someone. Her cousin, meanwhile, didn't dress as scary as she was, but the fact that she was having a big knife in her sweet getup was enough to terrify people. Never judge a book by its cover.

While the Baldwins looked like they were more than ready to cut down your flesh, the Willis sisters channeled their inner cowboy spirit in a western-themed outfit. Going all out, the daughters of Bruce Willis and Demi Moore even rocked fake beard and cowboy hats.

As Halloween was a little bit identical with darkness, it was no surprise to see some attendees went all-black for the annual party, though there were some who caught attention with their colorful fashion choice. For instance, Sarah Hyland decided to dress up as a taco while Ashley Greene cosplayed Robin Hood.
