The 2fm DJ, who co-hosts The Nicky Byrne Show, hosted a star-studded bash at Wineport Lodge today as she and her long-term love Kelly Keogh marked their nuptials in style.
Greene (34) popped the question in Portugal last September and both brides opted for ivory dresses for their big day.
It was a family affair both as Kelly and Jenny were walked up the aisle by their parents. And Jenny's father was involved in the planning from day one as she revealed he helped her choose a dress.
"He sent me a link and said, 'I've made you an appointment, check this place out and go into this range, I think you'll like it' - and I did," she said.
Guests included Nicky Byrne and his wife Georgina.
Jenny previously said her wedding would be "more like a festival" than a traditional ceremony and reception.
"If I think back a few years ago, I never thought we would (marry), and I personally never had an interest in getting civil-partnered," she said.
"I thought we'd either get married or we won't, so to be able to do that and have a full-on, proper wedding is brilliant."
"It's a different kind of wedding, and we didn't have to follow any of the usual traditions, which is great - so it makes it a bit more exciting and less stressful," she said.
