James Woods has a 20-year-old girlfriend. Go James.

For ex-M.I.T. student James Woods, the best revenge is the Revenge of the Nerd. "This is my whole entourage right here," the 59-year-old Woods told Lowdown at Wednesday's "Entourage" premiere, gripping his bodacious 20-year-old girlfriend, Ashley Madison, nee Myrick, apparently the daughter of one of Woods' golfing buddies. "That's it!" Woods added, laughing on the red carpet at NYU's Skirball Center for the Performing Arts. "What more do I need?" Good point. Ashley, whose low-cut halter top offered an ample view, was buoyant in more ways than one. "It was my birthday yesterday!" she gushed with cheerleader enthusiasm. "I've never gotten so many presents!" Gazing moonily at Woods - whose formerly gray hair has turned a very dark brown - Ashley added: "I can't believe he did that for me! It was unbelievable! So sweet!" She has a cameo role - as Woods' girlfriend, natch - in Sunday's "Entourage" season opener on HBO. Woods hilariously plays himself. "What's so funny about this character is he completely goes over the top about everything," he explained, "and because people think that's the way I am. It was fun to spoof." [NYDailyNews]
