The RTE presenter, who is single again at the age of 34, was looking far from heartbroken as she enjoyed some cocktails with the girls during the sun-kissed holiday in Spain.
The Carlow native is holidaying with her sister Linda and close pal Mary Kay Sheehy in Spain, where they have rented a villa.
Showing off her slim figure in a navy and red bikini, Kathryn was all smiles as she posed for holiday snaps and showed no sign of heartache following her split with boyfriend of five years, Enda Waters.
She rang in the New Year holding a cocktail as she laughed and joked along with the girls.
Kathryn and Garda Enda parted ways in July.
