The VIP columnist got her 2013 off to a flying start by squeezing in some quality time with her Carlow-born boyfriend, whom she has been seeing since last February.
The pair's relationship is continuing to go from strength-to-strength and they make sure to see each other regularly .
Last month, loved-up Yvonne posted a romantic pic of the pair of them together, writing how she "missed her man".
The previous month saw her flying over to Belgium to spend a week with John in Liege.
She was taking advantage of having some time off to herself, given that her three children Jack (13), Missy (11) and Ali (7) were in Australia with their dad. As proof of what a difference a year makes, she spent some of the holidays with the film producer while ex Ronan Keating caught up with girlfriend Storm Uechtritz.
The pair rang in the New Year -- though the Keatings still made sure to spend Christmas Day together as a family.
They were booked in to celebrate the day with a meal in the K Club.
