LOUISVILLE, Ky. (WDRB) -- A very happy birthday this weekend at the Louisville Zoo.

Not one, but two of their most popular residents celebrated birthdays.

Qannik the Polar Bear turned 6, and Helen the gorilla is now 59.

Both animals received special birthday cakes as zoo guests sang to them.

Qannik made national headlines when she was found in 2011 on the side of a mountain in Alaska after being separated from her mom and sibling.

Helen is one of the oldest gorillas in North America and has been at the zoo for the last 14 years.

"It's a pretty big day for us. We are really proud of how well Helen is doing. She doesn't have a whole lot of health problems, she moves around really well, and we are just super excited to share this moment with everybody," Gorilla Forrest Keeper Michelle Wise said.

Both animals are zoo ambassadors.
