There are two major Hollywood actors that are now nervous not because of their own films coming out, but rather because their equally talented sons are starting a career in show business at the same time, as Pierce Brosnan's son Dylan and Gary Oldman's boy Charlie make their modeling debuts during the Paris Menswear Week!

The former James Bond actor and the Oscar-nominated "Harry Potter" one aren't usual attendees at fashion shows, but the fact that Pierce Brosnan's son and Gary Oldman's son were making their runway debuts kept the proud dads in first-row seats in the French capital.

According to Yahoo! News, both actors were interviewed about their children's modeling debuts, and they showed completely different sides of being proud dads: while the "Mamma Mia!" actor kept it cool and said he and his wife Keely were there to support Pierce Brosnan's son Dylan, the "Dark Knight" star said he was feeling anxious over Charlie.

"I'm a little nervous for Charlie. The Yves Saint Laurent house is such a tradition ... It's great that he, in a small way, can be part of it," Oldman said before the show.

The Associated Press reports that it was fashion designer Hedi Slimane who discovered both Pierce Brosnan's son Dylan and Charlie Oldman, and Brosnan had already done some work for the major designer house in the past; a few months back, Dylan, along with another celebrity son (Val Kilmer's son Jack), was part of a new campaign directed at a younger YSL audience.

While Pierce Brosnan's son already has experience in the modeling scene, Fox Business reports that Charlie Oldman's a newcomer in the industry, having been discovered during a music concert wearing a jacket designed by the fashion house, something that immediately caught the eye of the people at YSL!

With Pierce Brosnan's son, Kilmer's and Oldman's, plus female supermodels Kendall Jenner and Cara Delevingne also hailing from famous families, one thing is clear: beauty and talent definitely comes in the genes for many in the catwalks!
