Mary Byrne just abseiled down one of Dublin’s tallest buildings

All for a good cause.

Announced as the newest celebrity ambassador for Make-A-Wish Ireland, Mary Byrne decided to take an active approach and abseil down one of Dublin’s tallest buildings today.

The event, named Rope for Hope, offers participants the once-in-a-lifetime chance to abseil 115 ft of State Street International on Dublin's Quays, while raising much needed funds for Make-A-Wish Ireland.

The former X-factor star said, “I’m delighted to become a Make-A-Wish Ireland ambassador. I’m a big believer the in the power of a wish-come-true, and no one deserves that more than a child who is battling a life-threatening illness.

“The joy and hope that Make-A-Wish Ireland brings to these children and their families is just incredible and I am delighted to help spread the word about the great work they do!”
