Pierce Brosnan has been a star for decades, but he’s more than happy to share the spotlight with his 18-year-old son Dylan, an up and coming model who made his first runway appearance in Paris last weekend at the Yves St. Laurent show.

"It is a proud moment. We're here to see our son on the runway. To support him," Pierce said prior to the start.

"He's not modeled before, and (designer) Hedi (Slimane) just discovered him at a juice bar coffee shop in Malibu," he added.

Dylan did a print campaign for the iconic French design house earlier this year. He was joined on the runway by another model with a famous pop, Charlie Oldman, whose father is British actor Gary Oldman.

Brosnan, a native of Co. Meath, has been spending lots of time in Dublin these past few weeks filming his starring part in the new thriller I.T. According to the Daily Mail, 62-year-young Pierce “plays a successful publisher whose relationship with a young I.T. consultant sours, and soon finds that his new enemy is using technology to threaten his family, business, and life.”

The film co-stars Anna Friel and Swedish actor Michael Nyqvist and has been shooting in several Dublin locations. Pierce has been pictured alongside thrilled fans taking selfies and signing autographs.
