It wasn't long ago (during Bey's pregnancy with Blue Ivy) that many believed the singer to be "faking" her baby bump and using a secret surrogate for vanity reasons (citing one or two instances as 'credible' evidence).
Mr. Carter himself (Jay-Z) has also been accused of fudging his age.
Last year, NY based DJ Troi Torain alleged that Hov was actually 50, and not 44; his claim was later disparaged as B.S.
While Bey-Bey hasn't commented on her dad's word vomit (and probably won't), who cares if it is true!
People lie about their age all the time.
Hell, it was only last year, 3 years after I graduated college, did I stop telling people I was a "recent college graduate."
If Bey wants to be 34 and she really isn't, she's 34 to me.
She will always be oppressively flawless, regardless of the ravages that come with being a mortal--which, news flash! she isn't a mortal, anyway!
