Ice cream maker Ben & Jerry's are jumping on the Yes bandwagon for the upcoming same-sex marriage referendum.

It is also part of the YEStivals, which will see the company taking to the road this April and May.

They say they are "scooping up free ice cream and social activism across the country."

The four-stop nationwide festival aims to spread awareness of the Yes Equality campaign, and empower people to use their voice in this year's referendum.

Actors Ian Lloyd Anderson and Emmet Kirwan, DJ and model Vogue Williams, comedian Joanne McNally and members of Dublin's GAA team Michael Darragh MacAuley and Rory O'Carroll appear in the advert - along with models Holly Carpenter and Thalia Heffernan.
