Remember Fiona, the baby hippo at the Cleveland zoo that was born premature and became a national celebrity earlier this year? The little lady isn’t through with her celebrity status, as she just apparently gave approval to a couple’s engagement in front of the hippopotamus enclosre at the zoo. Nick Kelble had just kneeled to propose to his sweetheart, Hayley Roll, when Fiona popped up in the enclosure beside them, pressing her face to the glass and watching the whole proposal. She seems pretty happy about the whole thing. The couple said they were happy that Fiona could be a part of their special day.
