Big Bang Theory star Simon Helberg looks worlds different than his nerdy character on the hit sitcom as he attended a red carpet event.

Six years after appearing as the dorky engineer Howard Joel Wolowitz on The Big Bang Theory, the now 44-year-old actor showed off his new handsome transformation. On Wednesday, April 9, Simon looked unrecognizable as he made an appearance at the star-studded AMC Networks Upfront event at Spring Studios in New York City.

Simon's former character on the show was known for his eccentric sense of style, often wearing ill-fitting clothing featuring bright in-your-face colors along with an unflattering bowl cut. But now, almost a decade later - Simon appeared to have a major glow-up as she showed off his new facial hair and trendy sense of style.

During the event, the comedian was seen with his hair grown out in long, luscious grey-and-black locks brushed over to the side along with a full beard. Along with the actor's new flattering facial hair and hair-do, Simon also showed off his impeccable sense of style as he stepped out in a blue denim blazer overtop a rust-colored button-down shirt.
