The long rumoured relationship between Jessica Simpson and John Mayer has finally gone public, as the couple spent the New Year together. But it looks like Mayer might be embarrased by his new love. According to In Touch, John didn't even tell his parents that he and Jessica are dating. Is there something he and Jessica are hiding?

Jessica Simpson has a smile on her face again -- and insiders say it's all thanks to singer John Mayer. But Jessica's friends are worried that she's more serious about John than he is about her. For example, when he went home to spend the recent holidays with his parents in Fairfield, Conn., he never even mentioned his new girlfriend. "Jessica didn't come up once in conversation," John's dad, Richard, tells In Touch exclusively. But Richard insists his son is "very private" about his love life. "We never pry," he tells In Touch.

"We never pry." "Jessica didn't come up once." Notice anything weird about those phrases? Sounds like they're hiding something, doesn't it? But what could be so shameful that it would have to be kept a secret? How about Jessica Simpson's Penis!

Or, should I say, Jessica Simpson's "not a penis." What the hell am I talking about? Watch this hilarious new leaked clip from MTV2's Crank Yankers to find out.

Crank Yankers is back Feb. 9 @ 10 pm on MTV2, and if the rest of the pranks are as funny as this one, it's going to be great.
