This just in - nine lucky ladies got a little more ice than they expected at the 2012 ZooLights at the Lincoln Park Zoo.

The event, which spreads more than 2 million twinkling bulbs throughout the zoo, brought 420,484 visitors to take in the show, a new record. At least 18 of those zoo lovers are now engaged, with the big question being popped under the twinkling lights, according to a press release from the zoo.

The Lincoln Park Zoo is always free and open 365 days a year. Staff call it "the perfect place to pop the question, whatever the season."
