corin_ : Companies don't hire famous people to "do the job". They hire them because they are famous. E.g. Alicia Keys at Blackberry, Rihanna at Puma, Will.I.Am at Intel. So, university degree is indeed utterly irrelevant.
Generally speaking disqualifying someone for not having a degree is (in my opinion, and many others but plenty disagree too) foolish, but if you're only considering her for being famous then nobody would even bother finding out if she had a degree.
