In celebration of Robert Pattinson‘s 25th birthday TODAY, InStyle took a look back at some his hottest red carpet moments ever. Since his transformative casting as Edward in the Twilight movie in 2008 to his recent blockbuster Water For Elephants, the red carpet style of this once unknown Harry Potter extra has definitely evolved. His signature look now includes colored suits, sleek jackets, and his famously unkempt coif. Even the things critics scrutinize him for—untucked shirts, a dodgy, shy demeanor, and his hair—are exactly what his fans adore most. This guy is a smooth Hollywood heartthrob in the making, if not already. And with that, we say Happy Birthday!
