The A list couple are instead going to treat themselves to a night in a hotel and a day's shopping.
The couple will mark two years together over the festive season
But instead of lavishing his model girlfriend with romantic gifts and expensive jewellery, Holly and her rugby star boyfriend have come up with an alternative plan to celebrate their second Christmas together.
“Myself and Cian decided not to buy each other presents this year,” Holly (22) told the Herald.
“Instead, we are going to spend a whole day together and go all-out with hotel, dinner and shopping.”
The pair have booked a day of indulgence over the Christmas holiday.
Holly said: “We have booked a night in the Westbury Hotel and we are going to go shopping for stuff that we really want instead of having to guess and we'll treat ourselves to a nice dinner as well.”
The Dublin couple will fit their time together in between Cian's rugby schedule and Holly's charity work. The striking brunette will spend Christmas Day with her dad when they will be dishing out dinners to homeless people.
