na, no link...but in terms of your question about today's info age...i think it's just such a common thing for entertainers to lie about their age that it actually becomes them after a while & even in the industry. it's like they all see it into existence & it just sticks with them, and everybody just goes with it because so many others are lying about their age anyway.
as for Beyonce being born in 77...my wife used to work for an agency that helped people in financial need, and a former closely associated exec assistant at the 40-40 club went. So, everybody that goes has to give their story, and my wife & her were talking. she said she's seen the jay/bey marriage certificate in the office, and beyonce's birth date says 1977.
in jay's case, i'm just going by the consistency of nas saying on Ether, 'you 36 in a karate class?" back in 2001 before jay turned 37...star also mentioned jay's real age back on hot97 when he was on the morning show in those days...and cam claimed he was 42 in 2006 back on that rant about "chancletas".
