House of the Dragon star Harry Collett poses in his Calvin Kleins for ad campaign

Young actor Harry Collett is best known for his work on House of the Dragon, where he plays Jacaerys Velaryon, aka Jace. Jace had a frustrating time in the show's second season. He has his own dragon, Vermax, that he can ride, but as the son of future queen Rhaenyra Targaryen he was discouraged from riding it lest a political rival shoot him out of the sky. His mother burdened him with the knowledge of a prophecy which every Targaryen ruler must work to fulfill, and he feels his birthright is threatened by a bunch of a new peasant dragon-riders who are putting their feet up on tables and using the flatware wrong and generally classing down the place.

How do you relax in a situation like that? Sometimes you need to let it all hang out. This is all a very tortured segue into telling you that Harry Collett posed wearing Calvin Klein underwear for a new ad campaign. He posted some of the pics to his Instagram:

Collett is the latest in a long line of celebrities who have stripped down for Calvin Klein campaigns; past notables include Mark Wahlberg, Justin Bieber, Vikings star Travis Fimmel, Michael B. Jordan, Jacob Elordi and Jeremy Allen White. Not bad company to keep.

As of right now, Collett doesn't seem to have any other film or TV projects on deck, but he will return as Jace in the third season of House of the Dragon, which recently started in on preproduction. When last we left House of the Dragon, the show was on the eve of a big battle called the Battle of the Gullet; without giving away spoilers, Jace is involved. We can expect to see that one pretty early on whenever new episodes of House of the Dragon start to drop in 2026.
