Holy hotness, Hermione! All grown up from her Harry Potter days, Emma Watson looks super-sexy in a denim shirt and jeans on the April cover of Elle.

With smoldering cateye makeup and sexy windswept hair, the 23-year-old actress strikes a sultry pose in the cotton shirt and calfskin pants by Balmain. In other images from her photo shoot, Watson shows off more of her slim figure in a plunging Anthony Vaccarello swimsuit. She also bares her midriff in a Rodarte crystal-beaded top and printed denim, embossed snakeskin, and silk shorts.

Though she's clearly successfully transitioned from child to adult star, Watson tells the magazine that growing up in the spotlight -- during puberty -- was rough. "There are all these actresses who have emerged in the last year or two, and they get to emerge as this complete human being," she said. "And I'm so jealous!"

As she continues to move forward with her career -- appearing next in Darren Aronofsky's $125 million blockbuster Noah -- Watson plans to try and maintain having a separate life outside of her career.

"I remember reading this thing that Elizabeth Taylor wrote. She had her first kiss in character. On a movie set. It really struck me," Watson told Elle. "I don't know how or why, but I had this sense that if I wasn't really careful, that could be me. That my first kiss could be in somebody else's clothes. And my experiences could all belong to someone else."
