When CollegeHumor founder and CEO Ricky Van Veen isn’t out on the town with his buddy John Mayer, he’s charming Brian Williams‘ pretty daughter, Allison. The recent Yale grad met Van Veen while filming a pilot for “Girls,” a sitcom about 20-somethings in New York that was picked up by HBO in January. Like Van Veen, she knows a thing or two about Internet sensations. She’s appeared in Web-video takeoffs of “Tik Tok,” “Hallelujah” and “Mad Men Theme Song with a Twist,” which drew more than 1 million views on YouTube. A rep for Van Veen said, “He doesn’t comment on his personal life.” Allison’s agent didn’t respond.
