Halloween [1] is over, and stars shared their extravagant costumes [2] in honour of the spooky occasion. Hailey Bieber shared a glimpse of her pal Kylie Jenner's witchy costume, from an upcoming episode of Bieber's "Who's in My Bathroom?" YouTube series [3]. Megan Thee Stallion was also one of the first to get in the spirit, kicking off the month by popping a jack-o'-lantern on her head [4] for a fun at-home photo shoot.
Maya Jama's annual Halloween [5] party was one we were really looking forward to, and it did not disappoint with Amelia Dimoldenberg, AJ Odudu, and Munya Chawawa leading the looks. Not to mention Jade Thirlwall's incredible costume that you just have to see.
