Alun has been on Twitter to thank Folly Farm Adventure Park and Zoo for their help in making his proposal "extra special".
The penguins had been centre of attention at Folly Farm - until Alun got down on one knee inside their enclosure.
Jamie-Lee couldn't hide her shock, but after she said 'yes' to his proposal, dozens of visitors gave them a round of applause.
Alun Davies surprised his girlfriend Jamie-Lee Jones by proposing in the penguin enclosure at Folly Farm in Pembrokeshire.
Alun got down on one knee to pop the question in front of dozens of visitors - and some of the zoo's feathered residents.
