He's not a hunky, heartbroken doctor but he plays one on TV.

In real life, however, hunky actor Jesse Williams is anything but heartbroken as he married his longtime girlfriend Aryn Drake-Lee Saturday in Los Angeles.

"Jesse was beaming with joy throughout the entire ceremony," a guest at the wedding told People. "It was the perfect night with lots of smiling, laughing and emotion. You could feel the love they have for each other. They're madly in love!"
