The ladies of Fifth Harmony are all about fall and Halloween!

Which Fifth Harmony Member Told Bailee Madison She Has 'A Beautiful Sweet Spirit'?

Ally Brooke Hernandez has been beaming over this season since it began.

The oldest 5H member even had a "late night baking" session a few weeks ago celebrating fall.

Her bandmate Lauren Jauregui has even followed in her fall baking footsteps, but Hernandez reigns as queen when it comes to fall baked goods.

She spent her Friday night hosting a twitcam to demonstrate how to bake pumpkin spice cookies.

"I HOPE Y'ALL HAD FUN AND ENJOYED THE CRAZINESS & COOKIES," Hernandez beamed after the fall baking video stream ended.

Normani Kordei Hamilton was hoping her bandmate would save her some of the fall treats.

Meanwhile, the youngest 5H member went to Knott's Berry Farm with her family to attend the perfect Halloween adventure known as Knott's Scary Farm.

Knott's Scary Farm has mazes, rides, "scare zones" and more.

"We had such a blast," Dinah Jane Hansen gushed while sharing a snap of her family together.

It sounds like the girl group members are getting in as much fall and Halloween-themed activities in stateside before they head over to Europe since they don't know what to expect over there.
