Are Dudes Not Down With Brit?: One possible destination for Jen on her "Getting Over John Journey" could be a Britney concert! And according to MTV News, Jen wouldn't be bothered there by too many men. At Brit's recent tour stop in Pittsburgh, the women in the audience reportedly outnumbered the men by a huge number. The men's restrooms are reportedly deserted during Brit's "Circus" concert. Most guys MTV talked to said, "I'm here with my girlfriend/ wife/ daughter." We can't help but doubt those men who accompanied their female loved ones still loved every second of the concert. It's 2009! Shouldn't everyone come out of the Britney closet?
