Mathew Horne, 41, has gone public with his new girlfriend Celina Basisli, 25, four months after he was first spotted passionately kissing her.
The Gavin And Stacey star - whose shock kiss marked the end of his nine-month engagement to Casualty actress Evelyn Hoskins, 31 - looked completely smitten with his new love - who acted as a designer on the show's Christmas special.
Attending the Night for Dreamers by Chicken Shed Theatre event in London on Thursday night, the actor cut a dapper figure as he cosied up to his sartorially savvy 'girlfriend'.

Mathew cut a dapper figure in an all-black ensemble while his other half slipped into a sensational slinky white dress.
She teamed the look with nude block high heels, while toting her belongings in a quirky handbag and accessorising with a dainty necklace.
Mathew's new love sported a shorter new fringed, blunt hairdo in comparison to her longer locks which she had when she was first seen kissing her new beau.
In July, Mathew was first seen kissing his new girlfriend in Burger King during a night out in Wales, where he was busy filming the Gavin And Stacey Christmas special.
