Fiona, the Cincinnati Zoo & Botanical Garden’s beloved baby hippopotamus, helped celebrate the engagement of #TeamFiona fans.

The couple were in line to snap a picture on their one-year anniversary earlier this month when Nick Kelble surprised Hayley Roll by getting down on one knee and proposing while Fiona photo-bombed the special moment at the zoo’s Hippo Cove.

Kelble, a University of Cincinnati student, and Roll, a recent Bowling Green State University grad and radiology tech at Cincinnati Children’s Hospital Medical Center, have loved Fiona from the start, our media partner WCPO-TV in Cincinnati reported.

“We are huge #TeamFiona fans and have been following her since she was born,” Roll said, WCPO reported. “We’re so happy Fiona could be there on our special day. Here’s to many more years of going to zoos with you,” Roll posted on Instagram.

One zoo staff member cropped the photo and quipped that Fiona thinks she’s the one getting engaged. Another said Fiona would need a much bigger ring for one of her toes.
