Fifth Harmony's Ally Brooke Hernandez revealed in a recent interview some never before heard details about Dinah Jane Hansen and Lauren Jauregui.

During an interview with Us Weekly, Hernandez was asked to play a game called "How Well Do You Know Your Squad?" She revealed that Hansen peed on herself while on stage on "The X Factor."

The 22-year-old recalled Hansen telling producers that she had to use the bathroom just before getting on stage, but was told to hold it because the group was about to perform.

"When the doors opened...that's when the show went on! She peed herself," Hernandez said.

The petite member of the group also dished on Lauren Jauregui's fear of heights. She called her band mate's phobia surprising, considering Jauregui is the most adventurous member of the group.

A look at Jauregui's Instagram account proves that the 19-year-old does enjoy traveling and trying new things, such as hiking and jumping off waterfalls, despite her fear.

Hernandez also revealed that she can do a great impersonation of Colombian pop star Shakira. She then proceeded to sing "Hips Don't Lie."

While the group is currently busy working on their followup to their 2015 debut "Reflection," Hernandez has found time to give back and take part in charitable causes.

Besides recently partnering with March of Dimes, she also visited Children's Health at the University Hospital in San Antonio, Texas.

The singer documented the Jan. 6 visit on Instagram and thanked the group's fans for helping to donate gifts to the hospital.

"Yesterday was a day that will forever be imprinted in my heart. Thank YOU, to the loving, caring, generous Harmonizers for donating an overwhelming amount of gifts to the children at the hospital. I had the honor of visiting these incredible kids and donating wagons of gifts on your behalf," she captioned the post.
