At a 30th anniversary party for Express in New York City, the English actor told MTV that he prefers to stuff his twig and berries into a Speedo instead of traditional trunks.
Asked what kind of swimsuit he wears to the beach, 22-year-old Westwick responded, "I don't specifically like the surfer ones."
When the interviewer asked if he wore banana hammocks, Westwick, who plays sleazy Chuck Bass on the hit CW show, replied, "Oh, always!" Then drove the Spandex question home with a definitive "Certainly."
For Westwick, baring his bulge in skimpy swimwear all comes down to confidence.
"I think it all has to do with how you wear it," said the actor, who recently split from "Gossip Girl" co-star/Op campaign face Jessica Szhor. "And that's for anything that has to do with clothes."
Let's just hope he doesn't feel the same way about Bieber bangs.
